Greater Than the Sum of Its Parts — Concurrent Alloy Design and Processing Science: An LMD Symposium Honoring Raymond Decker

Sponsored by: TMS Light Metals Division (LMD)
Organizers: Victoria M. Miller, University of Florida; Eric A. Nyberg, Tungsten Heavy Powder & Parts; J. Brian Jordon, University of Alabama; Wilhelmus H. Sillekens, European Space Agency; Neale R. Neelameggham, IND LLC; Vineet V. Joshi, Pacific Northwest National Laboratory

The most impactful developments in materials science are rarely just a new material or a new process; it is the simultaneous and complementary advancement of alloy and process together that can drive an innovation into the marketplace. Few researchers have adopted and been as successful with this design philosophy as Ray Decker.

Over his more than 50 years of experience as a research metallurgist, he has applied this over a wide range of alloys. His work in superalloys revealed alloying strategies for improved strength via coherency hardening. At the same time, his work revealed that trace elements from the crucible could play a role in the mechanical properties of the alloy. Developments in alloying strategy and improved heat treatments were equally critical in his work as a co-inventor of maraging steel. In his most recent venture, he has applied this philosophy to Mg alloys, developing and broadly commercializing thixomolding technology to obtain refined microstructures with high strength and retained ductility that are able to be thermomechanically processed without developing a deleterious amount of crystallographic texture. He has taken this processing technology and combined it with alloy design, resulting in his recent development of the BioMg 250 for bioabsorbable surgical implants. Thixomolding (or magnesium injection molding), as a light-alloy processing technology, was globalized by the vision of Ray and his partners in the commercialization of the semi-solid process through their company, Thixomat LLC. Leading Thixomat, Ray expanded the use of this technology from a few dozen thixomolding machines, to today where there are hundreds if not thousands of semi-solid, thixomolding machines through Thixomat and their affiliates. This has resulted in millions of parts for the video, cell phone, automotive, computer, and other industries being produced with improved properties, integrated part design, and net-shape manufacturing.

Over his career, Ray Decker has made critical technological advances to address challenges including reducing environmental damage, conserving energy, and making more effective orthopedic devices. In addition to his contributions as a technologist, he has consistently taken a long-term vision for his work by involving graduates and undergraduate students through strong collaborations with university faculty and volunteering through his professional societies. His career is certainly greater than the sum of its parts. It is the Light Metals Divisions great honor to recognize his lifetime of achievements at TMS2021.

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
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; and Shuai Wang, Southern University of Science and Technology.

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 TEM techniques in the areas of environmental TEM, thermomechanical testing, and 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.

Specific topics to be covered will include:

  • 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
