Abstract

{1 1 -2 2}〈1 1 -2 3〉 generalized stacking fault energies and {0 0 0 1} surface energies of a wide range of Mg-based binary alloy systems were computed using first-principles methods. The intrinsic ductility of these systems was evaluated, taking into consideration the probability of dislocation emission and crack propagation. A design map based on the intrinsic ductility was constructed. The results provide a basis for the design of high-ductility Mg alloys.
