                                                                                                                                                                            報告摘要:Interfaces are common planar defects in solids. Interface can act as barriers, sinks and sources for other defects. By tailoring interface structures and properties, materials can be designed to achieve unusual properties, such as high strength, good ductility, high toughness, and high irradiation tolerance. This can be accomplished through two steps: (1) Discover unusual mechanical behavior (e.g., high strength and good ductility) of nanostructured composites, and Develop theory and fundamental understanding of unusual mechanical behavior. (2) Transform fundamental understanding of structural characters and deformation physics of nanostructured composites into a mesoscale capability of discovering, predicting, and designing superior nanostructured materials (strength, ductility, toughness, radiation). To achieve this goal, multi-scale methods including experiment and theory and modeling are necessary. In this talk, I will present fundamental principles in developing interface/mcrostructure-dominated composites, and the developmentof experimental techniques and materials modeling tools at different scales.

He received his Ph.D from Rensselaer Polytechnic Institute, Troy, NY, USA, in 2006, and worked at Los Alamos National Laboratory (LANL) as technical staff member for 9 years. His research focuses on quantitatively exploring the structure-properties relations of structural and nanostructured materials using multi-scale theory, modeling and experimental methods and techniques. He was awarded the LANL Distinguished Postdoctoral Performance Award (2009), the LDRD/Early Career Award (2011), two LDRD-ER Awards (2013), TMS MPMD Young Leader Award (2013), International Plasticity Young Research Award (2015), Journal Outstanding Reviewer Awards forScriptaMaterialia (2016),Modelling and Simulation in Materials Science and Engineering (2016), and Acta Materialia (2017), and Materials Today 2018 Rising Star Award in the category of Materials Genome Innovation (2018). He served as Editorial Board of International Journal of Plasticity (2015~), Scientific Reports (2016~), and several others. He has published more than ~250 peer-reviewed papers (>9500 citations and H-index = 58, 25 papers selected as Hottest Articles in Materials Science, and 7 papers featured as Journal cover), and delivered 100+ invited/keynote presentations.
