报告摘要

In this talk, Dr. Cang Zhao will summarize his research in the fields of advanced manufacturing and impact mechanics. First, he will talk about dynamic behavior of nanocellular materials. The two most critical structural parameters of a cellular material are its porosity and pore size. According to the classical theory, the mechanical properties of cellular materials are only related to the porosity. So, the question is, where is the pore size or what is its role. Through systematic experimental investigations, Dr. Zhao will lead you to the answer. Next, he will present some results in x-ray vision of metal additive manufacturing. In this field, the community are mainly facing two problems: one is how to eliminate defects (e.g. porosity) and residual stress, and the other is how to control the grain and phase structures. Dr. Zhao will show the power of the high-speed x-ray imaging and diffraction techniques in shooting these two problems.
