Advances in Personal Protection (PPE) Strategies and Technologies

Dr. Eric Van Gieson, DARPA

Thursday April 22, 2021

Abstract

Chemical and biological threats have become increasingly ubiquitous and diverse. They present a risk to our stability operators in pandemic outbreak scenarios, and our warfighters serving in diverse operating environments. State-of-the-art protective equipment continues to severely limit mobility and performance of the user because of a dependence upon protective garments that are thick, heavy, and cumbersome. The Personalized Protective Biosystem (PPB) program aims to reduce protective equipment needs while increasing protection against existing and future CB threats.

PPB technologies will improve stability and provide flexibility for field-forward individuals operating in austere environments regardless of threat. This will be achieved with lightweight materials and adaptable, tissue-protective countermeasures acting independently, or as an ensemble, to provide on-demand, broad spectrum, and rapid protection. Most importantly, the program will leverage molecular components or commensal organisms at key points of vulnerability to remove protective equipment burden from the user. Successful PPB technologies would therefore change how the military and public health communities perform in unpredictable threat environments.

The Importance and Characterization of Residual Stress in Engineering Materials

Dr. Jeff Bunn, Oak Ridge National Laboratory

Tuesday December 08, 2020

Abstract

Studies utilizing neutron diffraction have been a consideration since the 1940s and are relatively commonplace today. Join us for a discussion on the background about the history of neutron diffraction, including the 50 plus year history of neutron research at Oak Ridge National Laboratory. Neutron diffraction has proven a valuable tool for materials characterization, specifically for the technique’s merits in residual stress mapping. Neutron diffraction allows for non-destructive spatial characterization of residual stresses in engineering materials with deep penetration, as opposed to x-ray diffraction which can only characterize the surface stress state. However, neutrons are not a common laboratory tool, and require large user facilities to be operated and maintained. This presentation will also include a basic overview of neutron diffraction in engineering materials and their use in mapping residual stresses in welding applications. For those interested, information on how users can access the neutron facilities at ORNL will be provided.

Advances in Materials Technologies for Nuclear Applications

Dr. Aladar Csontos, Electric Power Research Institute (EPRI)

Tuesday, October 13, 2020

Abstract

Two recent advances in materials technologies are poised to enable new capabilities and potential for the nuclear power industry. Currently licensed fuel designs in the majority of light water reactors use uranium dioxide fuel enclosed within a zirconium alloy cladding. Years of research accompanied by 60 years of commercial reactor operational experience have optimized these fuels to achieve economic and safe operation of the current nuclear plant fleet. The events at the Fukushima Daiichi nuclear power generating station coupled with recent material advancements have provided a strong motivation for the nuclear power industry, academia, and national laboratories to develop and transition to new fuel designs with an emphasis on improving safety, performance, and reliability for expected operating and accident conditions. However, for these Advanced Technology Fuels or Accident Tolerant Fuels (ATF) to achieve widespread adoption by the fleet of operating plants, they will need to provide additional safety and economic benefits over current fuels. In the course of developing the ATF technologies, novel approaches have been developed to monitor and assess fuel performance. Join us to discuss these novel, durable, and remote sensing technologies and the use of advanced robotics to inspect, monitor, and assess spent fuel and dry storage canister integrity for long-term storage applications.

High-Throughput Methodologies for Accelerated Design of Alloys

Dr. Ji-Cheng "JC" Zhao, Minta Martin Professor and Chair, Department of Materials Science and Engineering, University of Maryland College Park

Tuesday, October 8, 2019

Abstract:

This talk will review some recent advances in high-throughput experimental techniques for rapid collections of materials property data for simulations of materials properties. Localized property measurements on composition gradients created in diffusion multiples allow effective collection of composition-dependent properties, including thermal conductivity, heat capacity, coefficient of thermal expansion, and elastic constants. A newly developed forward-simulation analysis allows accurate measurement of impurity (dilute) diffusion coefficients from regular diffusion couple profiles without using isotope tracer experiments. The impurity diffusion coefficients together with interdiffusion coefficients are essential to the establishment of diffusion (mobility) databases for modeling the creep properties of materials and precipitation processes. Recent development of dual-anneal diffusion multiples (DADMs) allow rapid and systematic collection of phase precipitation kinetics and morphological evolution data across wide ranges of compositions as a function of time and temperature, creating large datasets for validation and testing of model simulations.

Blacksmithing 101 Demo

Nova Labs in Reston, VA
Saturday, March 2 at 6 pm (and dinner to follow at 8 pm)

Saturday, March 2, 2019

Blacksmithing 101

The chapter is doing something a little different this month! You are invited to observe a class covering the basics of blacksmithing. The class is free for audience and observers to listen -- and to find out if you would like to try blacksmithing at a future event. The 3 makers in the class will learn essential skills like hammer control, tapering, bending, and twisting as well as key safety items like how to avoid burning yourself, branding your friends, or hitting yourself with blunt objects.Those taking the class will leave with whatever metal they have beaten into submission.

This is also a great opportunity to take a look at NOVA Labs in Reston, VA, a membership-driven, all-volunteer makerspace, founded in 2011 with the purpose of empowering the community to rediscover the joy of making things.

WHAT YOU'RE GETTING INTO: The demo will take place in "blacksmithing alley" behind the lab, so dress in layers, as it might be chilly but there will also be fire. And also sparks. Class participants MUST wear non-synthetic clothes, including leather shoes and long pants, and the audience members should as well. Bring your own or borrow the Lab's safety glasses.

Dinner
We plan to head over toJackson's Mighty Fine Food and Lucky Lounge afterward for an 8pm dinner to discuss the finer points of beating metal into submission.

Atomic Layer Deposition (ALD) - An Enabling Technology for Space Systems

Dr. Vivek Dwivedi, NASA Goddard Space Flight Center

Wednesday, November 14, 2018

Abstract:

A key technology development driver in environmental control systems and next generation optics utilize thin film development borrowed from the semiconductor industry. We will start with a brief history of NASA and the Goddard Space Flight Center through its 60-year existence, and discuss how thin film technology has emerged as an enabling technology for optical and physical properties of spacecraft components in challenging environmental conditions in polar, geostationary or gravity neutral orbits. For example, depositing a layer of indium tin oxide (ITO) on a radiator surface dissipates charge buildup, and variable emittance coatings such as VO2 are used to optimize radiator size, allowing the heater power budget to decrease. The properties of these enhanced coatings must be tailored to mission-specific requirements.

The billion-dollar semiconductor industry has adopted Atomic Layer Deposition (ALD) for precision self-assembly and atomic-scale placement. ALD is a cost effective nanoadditive-manufacturing technique that allows for the conformal coating of substrates with atomic control in a benign temperature and pressure environment. Through the introduction of paired precursor gases, thin films can be deposited on many substrates ranging from glass, polymers, aerogels, metals, and powders, to high aspect-ratio micro- and nano-structures. With the resulting atomic-level control, the fabrication of metal transparent films, precise nano-laminates, and coatings of nano-channels and pores is achievable.

ALD has emerged as a powerful tool for many industrial and research applications. This technology benefits NASA in providing a novel method to facilitate the production, optimization, and protection of valuable spaceflight hardware. A method has been demonstrated for the ALD of In2O3 and films on a variety of substrates from Si(100) wafers, glass slides, and on Z93P pigments (patent pending). The results indicate excellent growth of 4 to 60 nm thick films demonstrating an order of magnitude decrease in resistivity on the pigments. Further examples in optics applications will be discussed.

About the speaker:

Dr. Vivek H. Dwivedi joined the Thermal Engineering and Analysis Branch at the NASA Goddard Space Flight Center in 2010 and is currently the Associate Branch Head. His interests include thin films, atomic layer deposition, open source software development, optics, heat and mass transfer involving high aspect ratio structures and new technology innovations. Prior to his current position, he worked as a senior space science visualization analyst at Goddard’s National Space Science Data Center with a specialization in large data set 3D visualizations. He completed his PhD in Chemical Engineering in 2010 while investigating an atomic layer deposition model in high aspect ratio geometries at University of Maryland, College Park. This work has led to the introduction of ALD at Goddard.​

Machine Learning for Materials Research: Autonomous Phase Mapping

Dr. Gilad Kusne, National Institute of Standards and Technology

Wednesday, October 24, 2018

Abstract:

The last few decades have seen significant advancements in materials research tools, allowing researchers to rapidly synthesis and characterize large numbers of samples - a major step toward high-throughput materials discovery. Machine learning has been tasked to aid in converting the collected materials property data into actionable knowledge, and more recently it has been used to assist in experiment design. In this talk we present the next step in machine learning for materials research - autonomous materials research systems. We first demonstrate autonomous measurement systems for phase mapping, followed by a discussion of ongoing work in building fully autonomous systems. For the autonomous measurement systems, machine learning controls X-ray diffraction measurement equipment both in the lab and at the beamline to identify phase maps from composition spreads with a minimum number of measurements. The algorithm also capitalizes on prior knowledge in the form of physics theory and external databases, both theory-based and experiment-based, to more rapidly hone in on the optimal results. Materials of interest include Fe-Ga-Pd, TiO2-SnO2-ZnO, and Mn-Ni-Ge.

About the speaker:

Dr. Gilad Kusne is a Staff Scientist with the National Institute of Standards and Technology (NIST). He integrates machine learning with physics theory, simulation, experiment, and databases to develop autonomous experiments for materials discovery and to provide live data analysis tools for experimentalists.

Dr. Kusne received his B.S., M.S., and Ph.D. degrees from Carnegie Mellon University, and is an Adjunct Professor with the University of Maryland.

Modeling Advances for Certification of Next Generation Materials

Dr. Ellen Cerreta, Los Alamos National Laboratory

Wednesday, May 9, 2018

Abstract:

Many DOE and DOD weapons program applications are demanding higher precision for certification and must meet multiple safety standards. For many years, large scale testing allowed for empirical understanding of stockpile relevant materials. Today, a physics-based understanding is required to certify use of new materials in weapons applications. For these reasons, significant investment has been made in enabling process-aware performance models for new stockpile materials. This is of particular interest for additive and other next-generation materials. In these models, the linkages between processing, microstructure, and material failure are examined to enable prediction of catastrophic failure during dynamic loading. These multi-length scale studies have identified a number of deterministic relationships between damage nucleation, damage growth, and microstructural features such as: inclusion/metal interface characteristics, bi-metal interfaces, grain boundary types, grain boundary orientation, and grain orientation. The tools utilized to advance predictive models for damage and failure in extreme environments as well as the work to design next generation materials for enhanced properties, particularly damage tolerance, will be discussed.

About the speaker:

Dr. Ellen Cerreta is the Deputy Division Leader for the Explosive Science and Shock Physics Division, at Los Alamos National Laboratory. Since coming to Los Alamos, she has examined the correlation of microstructure to mechanical response of metals and alloys, with the support of the Department of Energy's Office of Basic Energy Sciences, Weapons Program, and Laboratory Directed Research and Development (LDRD) funding.

Practically Brand New at 50!
Electron-excited Energy Dispersive X-ray Spectrometry (EDS) for Accurate, Precise and Sensitive Elemental Microanalysis, and So Can You! (EDS Replaces WDS!)

Dr. Dale E. Newbury, NIST Fellow

Abstract

Join us for a look back as well as forward at a core technology for materials science!

2018 will mark the 50th anniversary of semiconductor-based energy dispersive X-ray spectrometry (EDS) on an electron probe microanalyzer (EPMA) (Fitzgerald, Keil, and Heinrich, Science, v159 (1968) 528). EDS was quickly combined with the scanning electron microscope (SEM) to make X-ray microanalysis a widely available elemental characterization method with applications in the physical and biological sciences, technology, failure analysis, and forensic science.

Within its first decade, SEM/EDS demonstrated the capability of rigorous quantitative microanalysis matching EPMA/WDS in the absence of peak interference. The emergence of the silicon drift detector (SDD) implementation of EDS (Struder et al., Mikrochim. Acta, v15 (1998) 11) has provided much higher throughput (by a factor of 50 or more at the same resolution) combined with extraordinary peak stability in both shape and calibration, which is ideal for accurate peak fitting. This SDD-EDS performance enables collection of high count spectra (10 million counts or more within 100 s) that provide the basis for accurate, precise and sensitive quantitative analysis, despite severe peak interference and large differences in concentration. Even with severe interference from a major constituent (C > 0.1 mass fraction), trace constituents can be measured to C = 0.0005 (500 ppm) or less. Iterative qualitative analysis (i.e., peak identification) and standards-based quantitative analysis with careful inspection of the peak-fitting residual spectrum after each stage can reveal unexpected constituents hidden under high concentrations of interfering elements.

Trace analysis, low atomic number elements, low beam energy microanalysis, SEM/ EDS can do it all, effectively replacing EPMA/WDS for elemental microanalysis down to 500 ppm, and at much lower electron dose.

Materials Science vs. the San Francisco Oakland Bay Bridge

Stephen Christoffersen, AECOM International

Tuesday, May 3, 2016

Abstract:

The 1989 Loma Prieta earthquake severely damaged the East Span of the San Francisco-Oakland Bay Bridge. The Bridge serves as vital link in the Bay Area not only for commuters and movement of goods, but also as an emergency lifeline route. Replacing the East Span is the largest public works project in California history, valued at $6.5 billion.

The Bay Bridge sits over very poor soils and lies in a high seismic zone and is within miles of two major earthquake fault lines (San Andreas and Hayward). In order to satisfy the 150-year design life, high strength concrete, high strength cable wires, high strength structural steel, and high strength structural bolts and rods were required. During the first two weeks of March 2013, 32 of the 96, 3”-diameter, 20-foot A354 high strength rods, which tie-down the self-anchored suspension bridge superstructure, failed a few months from the scheduled opening of the East Span of the Bay Bridge. Please join Stephen Christoffersen to learn about the history, investigation, and resolution of this high-profile materials failure.

Interstitial Hardening Taken to a New Level: Paraequilibrium Carburization of Austenitic Stainless Steels

Art Heuer, Case Western Reserve University

Tuesday, November 10, 2015

Abstract:

Interstitial hardening of austenitic stainless steels at low temperatures, i.e. under paraequilibrium conditions, leads to massive increase in surface hardness (Rockwell C values of 70.5 or higher) without carbide or nitride formation. This “superhardness” is due to a “colossal” supersaturation of carbon/nitrogen interstitials (10-25 at %) and results in ~100x improvement in wear resistance, with essentially no loss in ductility of treated components. Furthermore, the interstitial concentration profiles resulting from the 1 atm. gas phase interstitial hardening leads to residual surface compressive stresses ≥ 3 GPa, which arise because the untreated core constrains the significant lattice expansion that would otherwise arise from the massive concentration of these interstitials. These residual compressive stresses dramatically improve the fatigue resistance. In particular, fatigue lifetimes are increased by up to ~100x, and the endurance limit is nearly doubled. Finally, and most surprisingly, the corrosion resistance of 316L stainless steel in seawater is significantly enhanced—in crevice corrosion tests, for example, it outperforms Ni-base alloys such as IN625.

About the speaker:

Materials Genome® and Materials Design

Dr. Zi-Kui Liu, Pennsylvania State University

Thursday, March 12, 2015

Abstract:

The word genome, when applied in non-biological contexts, connotes a fundamental building block toward a larger purpose. Dr. Liu's presentation will begin with the concept that the fundamental materials genome is encoded in the language of CALPHAD (calculation of phase diagrams) databases. Using CALPHAD, the properties of individual phases are modeled as functions of temperature, composition, and pressure and can be applied to materials processing design. Recent efforts have shown that analysis of stable and metastable microscopic configurations (called microstates) can be used to predict anomalous properties such as negative thermal expansion. The variation of these microstates as they mutate in response to external fields dictates the properties of a macroscopically homogeneous single phase. As a specific example, thermal expansion can be quantitatively shown to be normally positive, colossally positive, zero, negative, or infinitely negative. This capability may provide new routes for design of materials with extraordinary performance.

Perspectives on Digital Direct Manufacturing

Dr. William Coblenz

Wednesday, October 29, 2014

Abstract:

The evolution of 3D printing and related technologies is having a major impact in the manufacturing sector. The capability to build parts with form, fit, and function using digital technologies has been a focus of DARPA R&D investments in the early 1990s. Today, further advancement of digital direct manufacturing (DDM) will depend on research focused on the following challenges:

Establishing design allowables and qualification of manufactured components

Exploiting the separation of information and material content of components to increase design innovation

Developing machine capabilities for heterogeneous objects which can’t be manufactured by conventional methods

Increasing the ratio of machine productivity to capital cost to capture more of the mass manufacturing market

Much of the investment by the Department of Defense has been driven by the potential to reduce the cost of building low volume systems and and to reduce the time from print-to-part. The ability to field and target new systems and platforms quickly can enable more timely responses to new threats, but methods intended for mass manufacturing make such rapid insertion increasingly unaffordable. The commercial benefits of adoption of 3D printing and related technologies mirror that of defense with potential for both aggregation and disaggregation of value chains. Future success will depend upon combining new business models with the new technology.

About the speaker:

Dr. William Coblenz’s technical interests span the emerging development of new materials and manufacturing processes. His experience managing DARPA programs includes Ceramic Insertion to transition advanced ceramic components into fielded military systems; Ceramic Bearings to develop the technology base for ceramic hybrid bearings used in high performance mechanical systems; Solid Freeform Manufacturing to develop digitally driven tool-less manufacturing of ceramic and metallic components; and several development programs for novel processing of ceramic and metal matrix composites. The DARPA Disruptive Manufacturing Program focused on affordable and rapid low volume production processes and the Nano Composite Optical Ceramic Program developed new erosion resistant transparencies for the mid and far-IR windows.

Dr. Coblenz holds BS and MS degrees in Chemical Engineering from Worcester Polytechnic Institute; and, MS and PhD degrees in Ceramic Science from the Massachusetts Institute of Technology. He came to DARPA in 1990 from The Norton Company where he served as the key technologist for advanced ceramics. Previous R&D experience includes positions at the US National Bureau of Standards (now NIST), the US Naval Research Laboratory, and corporate R&D at the General Electric Company. Dr. Coblenz has authored or co-authored more than 20 technical papers and is listed as an inventor on eight patents.

Light Metals Revolutionizing the Auto Sector

Cars, Metals, and the Materials Genome Initiative

Mr. William Joost, Department of Energy (DoE)

Feb. 11, 2014

Abstract

Improved performance and manufacturability of lightweight structural materials is critical for many industries. In the automotive sector, reducing the weight of a vehicle, or “lightweighting”, is frequently cited as an approach that can support automakers in achieving improved fuel economy. However, many barriers exist to the implementation of lightweight structural materials such as aluminum alloys, magnesium alloys, advanced steels, and carbon fiber composites - improvements in material performance, manufacturability, and cost are all necessary for wider adoption. In 2011 the President announced the Materials Genome Initiative (MGI) which seeks to discover, develop, manufacture, and deploy advanced materials at least twice as fast as possible today, at a fraction of the cost through a combination of experimental tools, computational tools, and digital data. The methods, infrastructure, and philosophy supported by MGI provide unique opportunities for efficiently and rapidly addressing technical challenges in lightweight materials. A brief analysis of lightweighting energy impacts will be combined with a discussion of the technical challenges in several material systems. The growing field of Integrated Computational Materials Engineering (ICME) will be introduced, and opportunities for applying ICME will be discussed using automotive material examples. ICME will be contrasted against other applications of modeling and simulation with a focus on identifying the elements of an ICME approach, which are most beneficial to accelerated materials development. Examples of ongoing work in this area will be provided along with a discussion on future opportunities and pitfalls.

About the speaker

Will Joost joined the Vehicle Technologies Office at the U.S. Department of Energy in January, 2010 as a Materials Engineer and Technology Development Manager for lightweight materials. He is primarily focused on the development of automotive metals and joining technologies, managing research and development projects at the National Labs, with industry, and in academia. Will also participates in several inter-agency groups such as the OSTP Subcommittee for the Materials Genome Initiative and the Technical Advisory Board for the National Additive Manufacturing Innovation Institute. As a researcher, Will explores the use of atomistic computational techniques towards understanding the impact of interstitials and interfaces on deformation in titanium alloys.

Will holds a B.S. in Materials Engineering from RPI, a M.S. in Materials Science and Engineering from Arizona State University, and is a Ph.D. candidate in Materials Science and Engineering at the University of Maryland.

Solving Alloy Design and Processing Challenges: the Ongoing Revolution in Materials Engineering

Gernant E. Maurer PhD, FASM 2012-2013 ASM International President

November 14, 2013

Abstract:

The Material Genome Initiative (MGI) was announced in June 2011 and highlighted the revolution in materials engineering that has been gaining momentum for the last 20 years. The development of computational modeling tools along with ever advancing computational speeds are already having a great impact on alloy design, alloy processing and alloy applications. We are beginning to integrate these tools to rapidly develop engineering materials that will revolutionize the next generation of technology.

Dr. Maurer will give a high level overview of the MGI and its potential and challenges. He will also describe how new computational tools are being used to solve today's materials engineering problems. To make power generation systems more efficient, many are transitioning from stainless steels that operate below 600oC to advanced ultra-super critical steam turbines made with nickel-based alloys that can operate up to 760oC. This transition brings with it major metallurgical and economic challenges related to alloy design, melt processing, and fabrication of large components. New computational modeling tools will play a critical role in engineering solutions for alloy design, solidification, forging, and heat treatment. Because any solution also needs to be economically viable, the effect of processing yields and operational strategies on cost are considered. The use of powder metallurgy may also be a a cost-effective alternative to alloys that have traditionally been cast-wrought processed.

About the Speaker:

Dr. Gernant E. Maurer has held positions ranging from a research and development engineer to corporate technology officer at a billion dollar corporation. Gern’s technical expertise has been gained in new product development for applications in aerospace, energy, industrial, consumer, and medical markets. He has led research efforts that took full advantage of computational modeling to streamline alloy development and improve processes. All of these activities required full utilization of online data resources and technical information.

His professional activities include active leadership roles in international symposium committees and industrial task forces to solve industry wide problems. Many material engineers that he has hired and has worked with have risen to prominent technical positions in many companies.

Dr. Maurer received his B.E.S. from The Johns Hopkins University and his Ph.D. from Rensselaer Polytechnic Institute. An active member of ASM, Dr. Maurer has served and led numerous committees, councils and chapters including service on the Awards Policy Committee, Technical Programming Board, the Mohawk Valley Chapter as an Executive Committee member, vice chair and chair and is currently a senior advisor to the Lehigh Valley Chapter. Dr. Maurer became a Fellow of ASM in 1988 and received the William Hunt Eisenman Award in 2008. He served as President of ASM International during its 100th Anniversary year.

Accio Energy: Advanced Manufacturing and Materials Driven Innovation in Wind Energy

Dr. Dawn R. White

Tues. October 15, 2013

Abstract

Wind energy has been a huge success in the clean and renewable energy sector; the growth in installed capacity and the reduction of the cost of generation over the past decade or so have exceeded most expectations. Today’s large utility scale turbines trace their heritage largely to work done in Denmark in the 1970’s, and a light weight, three blade upwind turbine of 2MW design and built by the faculty and students of Tvind Denmark, commissioned in 1978. Extensive incremental improvements to this basic design have resulted in dramatically increased efficiency, lower cost, and size increases resulting in high per unit output. However, little fundamental innovation has occurred, and modern turbines, with 6MW turbines being tested, and 10MW units being proposed, are pushing the boundaries, in design, materials and manufacturability.

Accio Energy was founded to disrupt this industry by combining a new physical principal for wind generation (electrohydrodynamic wind energy) with a much lower cost, modular design. This modularity, enables the application of automotive rather than aircraft heritage manufacturing technology and economies of scale to its production with major cost impacts through the value chain. This presentation provides an overview of the EHD wind energy technology, the manufacturing driven business model behind it, and some thoughts about the role of entrepreneurship, manufacturing and technology disruption in large, traditional industries.

About the Speaker

Dr. Dawn White is creative engineering executive with extensive experience in technology start-up company formation and financing, advanced manufacturing, automotive, and contract R&D. She has a continuous record of commercial innovation in a range of materials processing fields, including welding and joining science, metal spray forming, intelligent processing of materials and rapid prototyping and tooling. Dawn is currently founder and President/CTO of Accio Energy, a wind energy start-up developing non-turbine based, no moving parts wind energy technology. Previously she founded the VC-backed, Ann Arbor-based Solidica, Inc. in January 2000 based on the Ultrasonic Consolidation rapid prototyping process, which Dr. White invented and commercialized as the Form-ation™ rapid prototyping machine.

Design and Manufacturing Trends in Modern Aircraft

Dr. David Furrer, Pratt and Whitney Aircraft

Wednesday, March 13, 2013

Abstract:

The unprecedented requirements in fuel efficiency, performance, and overall cost have introduced many challenges and opportunities in the development and deployment of materials for aircraft propulsion systems. Materials advances are being realized in the areas of increased material temperature, advanced coatings, as well as in high pressure and high temperature sealing, and overall component and system weight reduction. In additional to increased materials capabilities, reduction in component costs and time to delivery are driving many unique and advanced materials and process solutions. Computer-based modeling and simulation of manufacturing processes has become a near-standard part of current industrial design methods. Forged and cast components are being designed for end system application and for manufacturability through the use of simulation tools. Process models also provide critical information about the thermomechanical history of the materials being processed, such as temperature, time, strain, and strain-rate. The thermomechanical process models are being linked to microstructure evolution models and mechanical property models to provide needed location-specific predictions throughout the cross-section of components.
