研究方向一

功能金属基复合材料服役机理与行为研究

研究方向二

金属材料变形机理研究与力学性能预测

研究情况

研究通过界面科学与工程理解金属材料及金属基复合材料中的界面结构与特性,并设计与优化界面,进而开发并改进材料性能。界面的特殊性本质源于界面处原子排布及电子结构,以及相应热动力学特性。本人以阶梯型共格界面作为研究对象,以晶体学分析、原子尺度模拟结合电镜表征为研究手段,特征界面结构,理解界面机理,预测界面行为,从而实现材料设计的目的。研究成果包括:特征六方密排金属中三维孪晶结构,理解孪生三维生长及交互机理,建立孪晶变体选择准则等。相关研究成果以第一作者或通讯作者发表在Acta Materialia、Materials Research Letters、Scripta Materialia等SCI期刊上。博士与博士后期间参与美国能源部、美国国家科学基金等多个项目。
