摘　　要：1.Introduction Equimolar multicomponent design and maximized configurational entropy cause high-entropy alloys(HEAs)to have outstanding mechanical performance over a large temperature range from cryogenic temperatures up to room temperature[1-9].According to previous studies,deformation-induced twinning and phase transformation are two athermal transformations that significantly improve the mechanical performance of HEAs,especially those with face-centered cubic(FCC)structure[8,10-19].
