Keywords:High-entropy alloy、Chemical composition、Plastic deformation behavior、Stacking fault energy、Mean-square atomic displacement

We investigated plastic deformation behaviors of two non-equiatomic CrCoNi alloys by compression or (and) tension tests to see whether improved strength and ductility can be achieved simultaneously.
