IAMS Lecture Announcement
中研院原分所演講公告
Title: Modern physical metallurgy: Computational materials science in nanomaterials and nanotechnology
Speaker: Prof. Yu-Chieh Lo (Center for Elements Strategy Initiative for Structural Materials (ESISM), Kyoto University, Japan)
Time: 3:00 PM, January 15 (Friday)
Place: C.T. Chang Memorial Hall (4F), IAMS (本所4樓張昭鼎紀念講堂)
Contact: Dr. Jer-Lai Kuo 郭哲來博士
Abstract:
Atomistic simulations (e.g., molecular dynamics, kinetic Monte Carlo simulations and density functional theory calculations) have been proved invaluable in understanding the microscopic mechanisms of deformation from a fundamental perspective in the past decades. Nevertheless, the intrinsic spatial-temporal scale limits place certain restrictions and those limits cannot be overcome in the short time. For example, the time and length scales accessed by classical MD are typically ~1 ms and ~100nm. Due to such limitations, the kinetics of material behaviors from atomistic simulations may show deviation compared with experiments. Here two examples of combined track record on the fields of in situ TEM and computational modeling are introduced. Through combining with different theoretical methods, we may be able to overcome the limitations in atomistic approaches and validate our experiments in nanomaterials and nanotechnology. In the end, a coarse-grain approach based on microelasticity and kinetic Monte Carlo is presented to bridge the gap between atomistic simulations and continuum description in the study of metallic glass.
