2018年6月22日下午3:30-4:30,中南大学材料学院青年科协、粉末冶金国家重点实验室联合材料学院研究生会举办的青年学术沙龙第335场在特冶楼229顺利进行,材料科学与工程学院胡涛教授等师生到场参加。

报告会题目为“Modeling and Simulation of Grain Boundary Phases Transitions in Materials”,Stephen Yang教授首先从镍金属加入少量硫会发生脆断的现象出发,提出非晶化和双层晶界的假设。其后,以高分辨透射电子显微镜和对晶界相转化的建模和模拟为手段,对两种假设进行论证。其中,Stephen Yang教授着重介绍了以原子论为基础,通过模拟的手段构建晶界相图的方法与意义。报告结束后,Stephen Yang教授与在场师生进行了热烈的交流,细心回答了学生提出的问题,现场气氛十分活跃。

 

报告人简介

Dr Shengfeng Yang is an assistant professor in the Department of Mechanical Engineering at Indiana University-Purdue University Indianapolis(IUPUI). Before joining IUPUI, he was a postdoctoral researcher at the University of California, San Diego, where he was leading the development of a computational material science tool to construct interfacial phase diagrams for metallic alloys and ceramic materials. He received his Ph.D. degree in Mechanical Engineering from the University of Florida in 2014. Prior to this, he earned his bachelor’s degree in Engineering Mechanics and master’s degree in Solid Mechanics from Huazhong University of Science and Technology in China. He has been working on many national research projects, including research funded by NSF, DARPA, Department of Energy and most recently Department of Defense. His research interests include computational mechanics, multiscale-multiphysics modeling, and scientific computing with a particular focus on the thermo-mechanical and dynamical properties of materials including metallic alloys, ceramics, biological composite, and energy conversion and battery materials.
