Strong and Ductile High-Entropy Alloys for Cryogenic to Elevated Temperature Applications
Abstract
The tunable properties of multi-principal element alloys, also commonly known as high-entropy alloys (HEAs), provide a remarkable opportunity for the development of superior materials for critical structural applications that involve extreme conditions. In this talk, an optimization approach for HEAs, at both low and high-temperature ranges, will be described and related strengthening and deformation mechanisms will be discussed. Moreover, our latest work on the mechanical behavior and deformation of both FCC and BCC HEAs across a broad range of temperatures will be presented. In this lecture, I will describe an alloy design strategy for super formability at ambient temperature and related mechanisms, in the case of BCC refractory HEAs. Finally, the influence of a heterogeneous microstructure on the mechanical behavior of these HEAs, at both cryogenic and elevated temperatures, will be introduced.
Biography
Dr. Enrique J. Lavernia, currently Professor and holder of the M. Katherine Banks Chair Department of Materials Science and Engineering and J. Mike Walker ’66 Department of Mechanical Engineering, Texas A&M University College Station, Texas. Formerly Distinguished Professor in the Department of Materials Science and Engineering at the Samueli School of Engineering, and the former Provost and Executive Vice Chancellor for the University of California, Irvine from 2015 to 2020. He was previously engineering dean (2002-2008, and 2010-2015) at UC Davis and Distinguished Professor of Chemical Engineering and Materials Science. He also served as UC Davis’ provost and executive vice chancellor for two years (2008-2010).
In 2024 he received the Bruce Chalmers award from TMS and in 2022 Dr. Lavernia was recognized with ASM International, Albert Sauveur Achievement Award “for sustained and pioneering studies on the fundamental mechanisms that govern the interrelationship between processing, microstructure and mechanical behavior of structural materials.” He was elected as a Foreign Member of the Chinese Academy of Engineering in 2020. He also received the Acta Materialia Gold Medal in 2020. In 2019 Dr. Lavernia was awarded a Doctor of Science in Technology, honoris causa, by Aalto University, Helsinki, Finland. In 2018, he received the Distinguished Engineering Educator Award from the National Engineers’ Council, and in 2017, he became a member of the National Academy of Inventors.
Dr. Lavernia was elected to become a National Academy of Inventors Fellow in November 2016. Also in 2016, he received the Alexander von Humboldt Foundation Research Award as well as the Leadership Award from the TMS Society. In 2015 he was inducted into the Hispanic Hall of Fame by the HEENAC Great Minds in STEM. In 2014 he was awarded the TMS Fellows Award Class of 2014 by the Minerals, Metals and Materials Society.
Elected to the National Academy of Engineering in 2013, Dr. Lavernia is also a fellow of the Minerals, Metals and Materials Society, the Materials Research Society, the American Society of Mechanical Engineers, the American Association for the Advancement of Science, and ASM International. He is the recipient of the 2013 Edward DeMille Campbell Memorial Lectureship and the 2013 ASM International Gold Medal Award. Named Presidential Young Investigator by the National Science Foundation, Dr. Lavernia also received a Young Investigator Award from the Office of Naval Research. In 2011 he received the Hispanic Engineer National Achievement Award and the Society for the Advancement of Chicanos and Native Americans in Science Distinguished Scientist Award.
Dr. Lavernia has published over 680 journal papers, 231 conference papers, 2 books, 11 edited books/journals, and 21 book chapters and has been awarded 11 patents on topics ranging from nano-materials to aluminum alloys. His research interests include the synthesis and behavior of nanostructured, high entropy and multi-scale materials with particular emphasis on processing fundamentals and physical behavior; high temperature-high pressure atomization processes; and additive manufacturing. He earned his B.Sc. from Brown University in 1982, and his MSc. and Ph.D. degrees in 1984 and 1986, respectively from the Massachusetts Institute of Technology.
