摘要
Abstract
In this paper ,the molecular dynamics method was used to simulate the dis‐placement cascade of 3C‐SiC by using LAMMPS code .The evolution of simulated radia‐tion‐induced point defects by the displacement cascade was studied at different PKA initial directions and energy .The results show that the vacancy number is irrespective with the initial direction of PKA ,and the linear relationship exists between the vacancy number and PKA energy .The variations of the transient temperature distribution and thermal spikes were investigated during displacement cascade .Through analysis ,a high temperature region produces during displacement cascade .T he size of this region chan‐ging with time is not dependent on the PKA energy .关键词
