Symposium Alloy Behavior and Design Across Length-Scales: An SMD Symposium Honoring Easo George
Sponsorship TMS Structural Materials Division
TMS: High Temperature Alloys Committee
TMS: Mechanical Behavior of Materials Committee
Organizer(s) Michael J. Mills, Ohio State University
George M. Pharr, Texas A&M University
Robert O. Ritchie, University of California, Berkeley
Muralidharan Govindarajan, Oak Ridge National Laboratory
Scope This symposium is by invitation only.

Through his creativity and scientific excellence, Easo George has made seminal contributions to metallic materials research. During his long tenure at the Oak Ridge National Laboratory and the Alloy Behavior and Design Group, most recently as Governor’s Chair, he has led the nation’s most active alloy development research activities. His expertise in phase transformations and alloy processing has enabled innovations in intermetallics, refractory alloys, and high entropy alloys. His group’s research has provided insights in the wide-ranging topics of ductility and fracture behavior in intermetallics, deformation behavior of refractory metals, and compositional effects in high entropy alloys. In addition, his innovative work on the solidification of eutectic single crystal microstructures provided a unique pathway for creating small material volumes for exploring size effects in mechanical behavior. In addition to the impact of his group’s own research, he also generously enabled the research efforts of many collaborators by providing alloys with highly controlled chemistries and microstructures.

This symposium will provide a forum for presentation of topical advances in:
• Principles of alloy behavior and design
• Strategies for defeating the strength-ductility “trade-off”
• Compositionally complex (high entropy) alloys
• Small-scale mechanical behavior
• Links between deformation mechanisms and mechanical behavior
• Advanced metallic alloys and intermetallics for high temperature structural applications
