[1G19] MD simulations to evaluate effects of stacking fault energies on defect formation process in crystalline materials under neutron irradiation (2)

Daiki Nakanishi2, Yingjuan Yang2, Tomoya Kawabata2, *Taira Okita1, Mitsuhiro Itakura3 (1. Research into Artifacts, Center for Engineering, the University of Tokyo, 2. Department of Engineering, the University of Tokyo, 3. JAEA-CCSE)

Keywords:collision cascade, stacking fault energy, molecular dynamics simulations

面心立方金属を対象として、高エネルギー粒子入射下における結晶欠陥形成過程をMD法により定量化した。欠陥集合体が形成する条件において、その形態は材料物性の影響を受けることが明らかとなった。
