We adopt the modified embedded atom potentials based classical molecular dynamics in combination with the similar atomic environment method to investigate the effects of different short-range orders on the mechanical behaviors of NiCoFeCr under the tensile and shear load conditions. Results indicate that the tensile and shear loads induce the elastic deformation, non-evenly yield deformation, and evenly plastic deformation. The formation of partial dislocations and stacking faults' core as well as the twin is the key factor of plastic deformation. The short-range order enhances the strength of NiCoFeCr.
