摘要	As the slip mode plays an important role in dislocation evolution and mechanical behavior, the effects of the slip mode on the high-cycle fatigue behaviors of ultrafine-grained (UFG) Cu and Cu-Zn alloys were evaluated. It is found that the fatigue limits can be improved largely by changing the slip mode to hinder dynamic recovery and recrystallization through the addition of Zn in comparison with UFG Cu with wavy-slip mode because of the serious strain localization and microstructural instability of the latter.
