The first-principles calculations apply the optimizing substitutional alloying elements can enhance the creep resistance of magnesium-based alloys, which is estimated as the materials parameter expressed in terms of the stacking fault energy (SFE), based on both macroscopic phenomenological studies and mesoscopic dislocation theory. As the results, it is demonstrated that Y among the elements investigated in the present paper is the most promising element to improve a resistance of creep controlled by dislocation climb in magnesium-based solid solution.
