The flow stress falls down after a peak value with the increase of strain in other conditions, showing dynamic recrystallization. 而在其他条件下,应力达到峰值后随应变的增加而逐渐下降,表现出动态再结晶特征。
The results show that the high-rate deformation process of the electroformed shaped charge copper liner is a kind of dynamic recovery and recrystallization. 实验结果表明电铸铜药型罩的高速变形过程是一个动态回复和动态再结晶过程。
