Prediction of Pressure-Induced Structural Transition and Mechanical Properties of Mg Y from First-Principles Calculations
《Communications in Theoretical Physics》2016年第1期92-98,共7页濮春英 荀显超 宋海珍 张飞武 卢志文 周大伟 
Supported by the Henan Joint Funds of the National Natural Science Foundation of China under Grant Nos.U1304612,U1404608;the National Natural Science Foundation of China under Grant Nos.51501093,51374132;the Special Fund of the Theoretical Physics of China under Grant No.11247222;Postdoctoral Science Foundation of China under Grant No.2015M581767;Young Core Instructor Foundation of Henan Province under Grant No.2015GGJS-122
Using the particle swarm optimization algorithm on crystal structure prediction,we first predict that Mg Y alloy undergoes a first-order phase transition from Cs Cl phase to P4/NMM phase at about 55 GPa with a small v...
