[447] First-Principles Study of the Crystal Structure Prediction and Stacking Fault Energies in Basal and Second Pyramidal Slip Systems of Mg-Y Alloys

*Eiki KOSAKAMOTO1, Takao TSUMURAYA2, Shinji ANDO2 (1. Grad. Sch. Sci. Tech. Kumamoto Univ., 2. Magnesium Research Center, Kumamoto Univ)

Keywords:第一原理計算、Mg-Y合金、結晶構造探索、積層欠陥エネルギー

第一原理計算手法を用いてMg-Y合金の結晶構造探索を行った.得られた安定構造の底面,二次錐面に対する積層欠陥エネルギーを計算し,非底面すべり系の活性化メカニズムについて詳細な検討を進めた.
