英文摘要	Fatigue behaviors of the CoCrFeMnNi-based high-entropy alloy thin foils with different Al addition were investigated under dynamical bending fatigue loading. The results reveal that the Al addition can effectively decrease the cyclic strain localization and improve the fatigue resistance, which is associated with the reduced cyclic slip irreversibility. The physical reasons for such reduction can be attributed to the enhanced planar-slip ability induced by Al addition. Furthermore, the formation of BCC phases caused by 10 at.% Al addition also leads to a delay in the fatigue crack propagation.
