摘要

本文采用分子动力学方法模拟了辐射剂量对不同晶粒尺寸Fe-10Ni-20Cr合金试样力学性能的影响。结果表明，辐照试样的塑性应变总是在晶界三点交点附近的点缺陷簇中成核，这是由层错产生引起的。结果表明，随着辐照剂量的增加，细晶试样的弹性极限比粗晶试样高，且降低速度慢。

Deformation behavior of Fe-10Ni-20Cr alloy at different irradiation doses

The paper presents molecular dynamics simulation of the radiation dose effect on mechanical properties of the Fe-10Ni-20Cr alloy samples having different grain size. It is shown that plastic strain of irradiated samples always nucleates in clusters of point defects locating near grain-boundary triple point intersections and caused by the stacking fault generation. It is found that the elastic limit in the fine grain sample, is higher and reduces more slowly with increasing irradiation dose than in the coarse grain sample.
