Grain refinement has been proved to be an effective route to improve the mechanical properties of the Mg-Al alloys which are known as the lightest structural metallic materials [1-3]. Among many grain..., the addition of alkaline-earth elements (Ca and Sr) is another important grain refining method for the Mg-Al alloys [4,5,14-17]. Due to the strong segregating power in the magnesium melt......
