Assessing the magnetic order dependent γ-surface of Cr-Co-Ni alloys

In order to efficiently explore the nearly infinite composition space in multicomponent solid solution alloys for reaching higher mechanical performance, it is important establish predictive design strategies using computation-aided methods. Here, ab initio calculations we systematically study effects of magnetism and chemical on generalized stacking fault energy surface (γ-surface) Cr-Co-Ni medium entropy show that both chemistry coupled magnetic state strongly affect γ-surface, consequently, primary deformation modes. The relations among various stable unstable energies are revealed discussed. present findings useful studying behaviors facilitate a density functional theory based transformation-induced plasticity twinning-induced mechanisms alloys.
