This symposium is linked with the REWAS 2022 sessions, as Dr. Apelian’s research is deeply coupled to the key themes within REWAS.
Failure, and a Career That is Anything But: An LMD Symposium Honoring J. Wayne Jones
Sponsored by: TMS Light Metals Division (LMD); TMS Magnesium Committee
Victoria M. Miller, University of Florida; Michael J. Caton, U.S. Air Force Research Laboratory; Nikhilesh Chawla, Purdue University; Trevor S. Harding, California Polytechnic State University; Paul E. Krajewski, General Motors Corporation; Tresa M. Pollock, University of California, Santa Barbara
About the Symposium
To study materials performance is to push materials to their limits—in creep, in fatigue, and in other demanding environmental conditions. It is to push materials to failure, then to engineer against those failure mechanisms. Over the course of Professor J. Wayne Jones’ career, he advanced the state of the art in the study of failure both for creep and fatigue. In the realm of fatigue, he is one of the pioneers of ultrasonic fatigue testing, demonstrating the existence of a fatigue limit for fcc metals in the ultra-high cycle regime. He has worked on a wide range of materials, from light alloys such as magnesium and aluminum to heavier alloys such as nickel superalloys, to less traditional materials such as metal-matrix composites and intermetallics.
Later in his career, Jones partnered with the Detroit automotive industry and Thixomat, studying both creep and fatigue in lightweight magnesium alloys. He also worked with the automotive industry to develop lightweight metal-matrix composites with high strength and high stiffness. He sought new probabilistic treatments for microstructurally informed fatigue crack nucleation models which could lead to improved lifing predictions.
Throughout his career, Jones has been a devoted teacher, not only in the classroom but to everyone he interacts with. Just as he has helped to develop alloy systems toward maturity, he has helped many generations of students and young researchers to achieve academic maturity. The Light Metals Division is honored to celebrate his career with this symposium.
This symposium will honor the breadth of his career with talks primarily in the areas of creep and fatigue, with microstructure-sensitive predictions and novel testing/prediction methodologies a particular focus.
Magnetics and the Critical Materials Challenge: An FMD Symposium Honoring Matthew J. Kramer
Sponsored by: TMS Functional Materials Division; TMS Magnetic Materials Committee
Organizers: Scott McCall, Lawrence Livermore National Laboratory; Ryan T. Ott, Ames Laboratory
About the Symposium
The increasing need for improved energy efficiency in numerous technologies drives the need for the development of advanced magnetic metals. For example, improvements in hard and soft magnetic materials are essential to enabling high-efficiency energy conversion technologies such as compact motor-generators. Similarly, caloric materials show great promise for increased cooling efficiency and longer operational lifespans, while eliminating greenhouse gases (many refrigerant gases have 1500-4000X the atmospheric warming potential of CO2). Beyond improved performance, these materials must also address critical materials challenges—where supply chain uncertainty can hamper widespread commercialization. For example, high-performance magnetic and magneto-responsive materials typically rely on rare earth elements, which are subject to supply/demand instability leading to dramatic changes in price. Disruption of the Nd supply in 2011 led to an increase in price by a factor of ten! Other technologies are enabled by minor metals such as gallium which is a co-product from aluminum mining. Demand for Ga is rapidly growing within the semiconductor industry (GaN), limiting its availability and increasing the cost for applications such as Galfenol—a magnetostrictive material. Therefore, there is a clear need to develop classes of advanced magnetic materials with decreased reliance on critical elements. Addressing this challenge requires developing new synthesis approaches for structures difficult to realize and advanced characterization to identify and optimize material performance. Synthesis techniques include pathways to: 1) Obtain and retain metastable phases and/or nanostructures in complex systems; 2) Scale-up synthesis to bulk geometries while maintaining non-equilibrium phases/structures; and 3) Precise control over chemistry, texture, and defects during synthesis. Equally important is advanced characterization of functional materials including: 1) Advanced electron microscopy characterization of atomic- and nano-scale structures; 2) In situ characterization (X-ray, neutron, etc.) of phase stability in complex systems; and 3) Physical property measurements.
This symposium will cover all aspects of advanced synthesis and characterization of high-performance functional materials. Specific topics covered will include permanent magnet materials (rare earth and rare earth free), soft magnetic materials, calorics (magneto and elasto), and magnetostrictive materials.
Primary Aluminum Industry - Energy and Emission Reductions: An LMD Symposium in Honor of Halvor Kvande
Sponsored by: TMS Light Metals Division; TMS Aluminum Committee
Organizer: Arne P. Ratvik, SINTEF
About the Symposium
A dedicated session for Halvor Kvande is planned as part of the Aluminum Reduction Technology symposium at the TMS 2022 Annual Meeting & Exhibition. Talks will not only highlight Kvande’s contributions to the industry but will also address improvements and challenges related to energy and emissions in primary aluminum production.
This session was originally planned in 2021 under the name of Aluminum Reduction Technology Across the Decades: An LMD Symposium Honoring Alton T. Tabereaux, Halvor Kvande and Harald A. Øye. Kvande’s session, however, was postponed and will be celebrated at TMS2022.
Seeing is Believing -- Understanding Environmental Degradation and Mechanical Response Using Advanced Characterization Techniques: An SMD Symposium in Honor of Ian M. Robertson
Sponsored by: TMS Extraction and Processing Division, TMS Materials Processing and Manufacturing Division, and TMS Structural Materials Division; TMS Chemistry and Physics of Materials Committee, TMS Corrosion and Environmental Effects Committee, TMS Mechanical Behavior of Materials Committee, and TMS Nuclear Materials Committee
Organizers: Kaila Morgen Bertsch, Lawrence Livermore National Laboratory; Khalid Hattar, Sandia National Laboratories; Josh Kacher, Georgia Institute of Technology; Bai Cui, University of Nebraska-Lincoln; Benjamin P. Eftink, Los Alamos National Laboratory; Stephen D. House, University of Pittsburgh; May L. Martin, University of Illinois - Urbana-Champaign; Kelly E. Nygren, Cornell High Energy Synchrotron Source; Blythe Gore Clark, Sandia National Laboratories; Shuai Wang, Southern University of Science and Technology
About the Symposium
Since his arrival in the United States in 1982 with a Doctor of Metallurgy from the University of Oxford, Ian M. Robertson has advanced our physical understanding of materials response under extreme conditions, including gaseous hydrogen atmospheres, corrosive environments, high stress/strain rates, and exposure to radiation. Over forty years of research at the University of Illinois Urbana-Champaign and Wisconsin-Madison, he has pioneered a range of in situ transmission electron microscopy (TEM) techniques in the areas of environmental TEM, thermomechanical testing, and microelectromechanical systems (MEMS)-based quantitative mechanical testing, as well as advanced focused ion beam (FIB)-based sample preparation. These techniques were developed with the goal of elucidating the basic physical mechanisms governing plasticity, material degradation, and failure processes. The contributions from his lab permitted the development, refinement, and validation of many theories and theoretical models, most notably the Hydrogen-Enhanced Localized Plasticity (HELP) mechanism for hydrogen embrittlement and determining the criteria for dislocation-grain boundary interactions. His research coupling TEM with advanced theory and simulation has shaped the current state-of-the-art in multiple fields and continues to be applied to increasingly complex materials and environments.
This symposium will feature talks on the following topics:
- Development of advanced in situ TEM techniques
- Analysis of late-stage plasticity near crack tips and fracture surfaces
- Understanding hydrogen embrittlement mechanisms
- Exploring the fundamentals of stress corrosion cracking
- Investigating dislocation-interface interactions
- Quantifying the stability of materials to irradiation damage
This symposium was rescheduled from the TMS 2021 Virtual Annual Meeting & Exhibition.
