摘要	The bending fatigue performance of the Al15(CoCrNi)85 medium-entropy alloy (MEA) with deformable multi-component duplex BCC phases was investigated. The significantly enhanced fatigue resistance is attributed to the reduced cyclic strain localization, which originates essentially from the duplex BCC phases and the Al addition in the FCC matrix. Al addition in the FCC matrix might enhance the planar slip, which is beneficial for the reduction of the slip irreversibility of dislocations and the cyclic strain localization. The deformable duplex BCC phases with the semi-coherent interfaces efficiently coordinate the incompatible plastic deformation, which would help release the local stress concentration at the phase boundaries. By comparing to the widely used micro-electro-mechanical system (MEMS) material, the Al15(CoCrNi)85 MEA with superior fatigue performance might be accepted as a promising material for micromechanical parts in MEMS.
