  3. MMAE Seminar - Dr. Amit Misra - Designing Metallic Nanocomposites for High Strength and Damage Tolerance

Armour College of Engineering's Mechanical, Materials, and Aerospace Engineering Department will welcome Dr. Amit Misra, Professor and Chair of the Department of Materials Science and Engineering (MSE) at the University of Michigan, Ann Arbor, on Wednesday, October 24th, to present his lecture, Designing Metallic Nanocomposites for High Strength and Damage Tolerance.

Abstract

Nanolayered composites such as Cu-Nb are used as model systems to explore the interaction of interphase boundaries with defects introduced via plastic deformation or ion irradiation. The results of these experimental studies are integrated with atomistic modeling and dislocation theory to provide insight into the unprecedented combination of properties achieved in certain nanolayered composites such as ultra-high flow strengths, high plastic flow stability, high fatigue strength, high thermal stability, high sink strength for radiation-induced point defects and trapping of helium in the form of stable clusters at interfaces. The results on "bottom-up" synthesized model systems are compared with "top down" accumulative roll bonding (ARB) processed bulk Cu-Nb nanolayered composites. A quantification of the defect-interface interactions as well as the processing-interface structure relationship allows the development of materials design concepts with controlled interface structures in nanocomposites to achieve tailored response in engineering applications.

Biography

Dr. Amit Misra is a Professor and Chair of the Department of Materials Science and Engineering (MSE) at the University of Michigan, Ann Arbor since 2014. Prior to that he worked at Los Alamos National Laboratory, New Mexico (LANL) from 1996 to 2014. At LANL, his most recent appointment was as the Director of a US Department of Energy, Office of Basic Energy Sciences (DOE/BES) funded Energy Frontier Research Center (EFRC) titled Center for Materials at Irradiation and Mechanical Extremes. Dr. Misra holds a PhD in Materials Science and Engineering from University of Michigan (1994) and BS in Metallurgical Engineering (1989) from IIT-BHU, India. His primary research expertise is in design of advanced structural metallic materials for tailored response in extreme environments for next-generation of automotive, aerospace, defense and nuclear energy technologies. Dr. Misra has mentored over 30 early career scientists and engineers (postdocs and graduate students). He has co-authored over 300 peer-reviewed publications.
