报告题目：Progress in Heterostructured Materials
报 告 人：Yuntian Zhu（朱运田）教授，香港城市大学
Strong and tough materials are desired for light-weight applications such as electric cars and aerospace applications Recently, heterostructures are found to produce unprecedented strength and ductility that are considered impossible from our text book knowledge and materials history. Heterostructured materials consist of heterogeneous zones with dramatic (>100%) variations in mechanical and/or physical properties. The interaction in these hetero-zones produces a synergistic effect where the integrated property exceeds the prediction by the rule-of-mixtures. Importantly, HS materials can be produced by current industrial facilities at large scale and low cost. There are many scientific issues with such materials that challenge the communities of experimental materials science and computational materials mechanics. Heterostructured materials is quickly becoming a hot research field with multiple international conference/workshops organized in different countries per year. In this talk I’ll present the progress in heterostructred materials as well as future challenges and issues.
Yuntian Zhu has recently joined the City University of Hong Kong as a Chair Professor, before which he was a Distinguished Professor in North Carolina State University, where he worked from 2007 to 2020. He worked as a postdoc, staff member and team leader in Los Alamos National Laboratory (LANL) until 2007 after obtaining his Ph.D. degree from the University of Texas at Austin in 1994. In recent years has focused on the deformation mechanisms at dislocation level and mechanical behaviors of heteroustructured materials, nano/ultrafine-grained materials, and carbon nanotube composites. He is an experimentalist with primary interest in fundamental aspects of materials research and also in designing materials with superior strength and ductility. He and his colleagues are pioneers of the emerging field of heterostructured materials. As of March 7,2002, his publication has been collectively cited for over 47000 times with h-index of 113 according to Google scholar. He recently received the institute of Metals Lecture and Robert Franklin Mehl Award. ASM international Albert Sauveur Award. IUMRS Smiya Award. TMS SMD Distinguished Scientist/Engineer Award, and TMS Leadership Award. He has been selected Fellows of TMS, MRS, APS, ASM, and AAAS.
