摘要: 通过对回收Cu射流杵体的金相分析得出药型罩在冲击波和挤压剪切变形双重作用下造成晶粒细化和温度升高，并为动态超塑性变形创造了条件，因此在形成射流之前材料已满足动态超塑性变形的条件，同时说明聚能装药射流的动态超塑性变形符合细小晶粒的转动变形机理。

Abstract: In this paper, we analyze the metallographes of the recovered Cu slug and get the results of reduction in the recrystallized grain size and rise in the temperature, which were caused by the two action processes, i.e. the shock wave action in the liner and the following squeeze-shear plastic deformation of the liner. The analysed result shows that the dynamic superplastic deformation conditions for liner materials were satisfied before the jet was formed. Meanwhile the process of a dynamic superplastics deformation is consistent with a mechanically driven subgrain rotation mechanism.
