Title: High Entropy Materials
Host: Dr. Robert Ritchie, University of California in Berkeley
Dr. Bernd Gludovatz, UNSW Sydney
Dr. Peter K. Liaw, The University of Tennessee, Knoxville
Dr. Qian Yu, Zhejiang University
High entropy materials have taken the field of materials science by storm over the past two decades, judging by the volume of current research and number of publications. These are materials consisting of multiple elements in which no single element can be considered the principal (or base) element. Especially for metallic alloys, these materials are variously referred to as high-entropy alloys (HEAs), compositionally complex alloys (CCAs), or multi-principal element alloys (MPEAs). There is also currently much interest in high-entropy ceramics (HECs). This is a vast compositional space, that has only sparingly been explored so far. The talks in this webinar will explore some aspects of the development, understanding, and applications of high entropy materials to provide a flavor of the current ongoing research in this area as well as near term opportunities. The talks will complement the February theme issue of MRS Bulletin on this topic, as well as symposia at upcoming ASM and MRS Meetings.
In this webinar, attendees will learn about:

Robert O. Ritchie is the Chua Distinguished Professor of Engineering in the Departments of Materials Science & Engineering and Mechanical Engineering at the University of California in Berkeley; he is also Faculty Senior Scientist at the Lawrence Berkeley National Laboratory. He received his M.A., Ph.D., and Sc.D. all from Cambridge University. Prior to joining the Berkeley faculty in 1981, he was Associate Professor of Mechanical Engineering at M.I.T. He is known for his research into the mechanics and mechanisms of fracture and fatigue of a broad range of structural and biological materials including, most recently, high-entropy alloys. He is a Fellow of the Royal Society in London, the U.S. National Academy of Engineering, and the U.K. Royal Academy of Engineering.
Bernd Gludovatz is a Scientia Associate Professor and ARC Future Fellow in the School of Mechanical and Manufacturing Engineering at UNSW Sydney. He received both his M.S. and his Ph.D. in materials science and engineering at the University of Leoben in Austria before working as post-doctoral fellow at the Materials Sciences Division of the Lawrence Berkeley National Laboratory in the U.S. His work focuses on the mechanisms underlying deformation, fracture, and fatigue of advanced structural alloys, nature-inspired composites and biological materials.
Peter K. Liaw obtained his B.S. in physics from the National Tsing Hua University, Taiwan, and his Ph.D. in materials science and engineering from Northwestern University. After working at the Westinghouse Research and Development (R&D) Center for thirteen years, he joined the faculty and became an Endowed Ivan Racheff Chair of Excellence in the Department of Materials Science and Engineering at the University of Tennessee (UT), Knoxville in March 1993. He has worked in the areas of fatigue, fracture, nondestructive evaluation, and life-prediction methodologies of structural alloys and composites. Since joining UT, his research interests include mechanical behavior, neutron and synchrotron diffraction, bulk-metallic glasses, high-entropy alloys, and processing of high-temperature alloys and ceramic-matrix composites and coatings. He was awarded the Royal E. Cabell Fellowship at Northwestern University. He is the recipient of numerous outstanding performance awards from the Westinghouse R&D Center. He was the chair of The Minerals, Metals and Materials Society (TMS) Mechanical Metallurgy Committee, and chair of the ASM Flow and Fracture Committee. He has been the chair and member of the TMS Award Committee on Application to Practice, Educator, and Leadership Awards. Liaw is a Fellow of ASM and TMS. He has been given the Outstanding Teacher Award, the Moses E. and Mayme Brooks Distinguished Professor Award, the Engineering Research Fellow Awards, the National Alumni Association Distinguished Service Professor Award, the L.R. Hesler Award, and the John Fisher Professorship at UT; the TMS Distinguished Service Award; and had a 2020 TMS Symposium dedicated to him.
Qian Yu earned her Ph.D. in materials science and engineering from University of California at Berkeley in 2012. She was a postdoctoral researcher at National Center for Electron Microscopy at Lawrence Berkeley National Lab and UC Berkeley from 2012 to 2014. She joined the faculty of the Center for Electron Microscopy at Zhejiang University in 2014, where she is also a professor in the Department of Materials Science and Engineering. Yu is interested in materials characterization. Specifically, her research interests focus on applying in situ electron microscopy techniques to probe into the correlations between structure and properties of materials. Her research work has been published in Nature, Science, Nature Materials, and Nature Communications. Yu gave more than 30 invited presentations at international conferences organized by MRS, TMS, and M&M. Her current interest is in titanium alloys and high entropy alloys.
