Traditional diffuse-controlled recrystallization mechanism can not account for the microstructural evolution in ASB.This indicated that diffuse is not the only controlled factor for recrystallization under high-strain-rate deformation.

• 表明在高应变速率变形条件下，扩散不是控制动态再结晶的唯一因素，应用一种基于力学辅助的动态再结晶机制能够较好地解释其内的微观组织变化。
