连续动态再结晶与层错能的关系？A review of dynamic recrystallization phenomena in metallic materials 2.2.1. Stacking fault energy In summary, the SFE determines the width of stacking fault which influences the level of dislocations dissociation into partial dislocations. Low γSFE promotes such a dissociation reactionwhich hinders the climb and cross slip of dislocations, i.e., retards DRV. This explains why CDRX and GDRX are generally observed for high γSFE while DDRX is expected for materials with low γSFE. It should be emphasized that γSFE is not the only factor to determine which type of DRX processes will take place during hot deformation, other influencing factors, which also play important roles in DRX, will be discussed in the following sections.查看更多
