摘要: 本文采用分子动力学模拟方法分别在辐照温度为600 K，三种不同PKA能量2 keV、6 keV和10 keV及两个不同PKA入射方向为和方向的条件下开展了α-Zr晶体内级联形成和发展的研究。模拟结果表明：在保持辐照温度为600 K不变的条件下，PKA初始入射方向为的级联体积均是大于方向的级联体积。级联尺寸随着PKA的晶体温度、能量的增加而增加，但与PKA的初始入射方向无关。
Abstract: The formation and development of cascade in α-Zr crystals at sample temperatures T = 600 K, en-ergy of 2, 6 and 10 keV and initially driving directions and of primary knock atoms (PKA) are investigated by molecular dynamics. The simulation results show that the cascades volume for the initial direction of PKA motion is greater than that of the initial direction at same all other parameters as temperature is 600 K. The size of cascade is increased with the increasing PKA energy and crystal temperature. However, it is regardless of initial direction of primary knock-on atom (PKA).
