It is necessary for cast alloys possessing sufficient plasticity to be subjected to deforming progresses for the improvement of mechanical properties. Developing as-cast magnesium alloys with appreciated plasticity is therefore important to the variety of wrought magnesium alloys and the enlargement of their applications. In this paper, the research progresses of Mg-Al, Mg-Li, Mg-Zn and Mg-RE (rare earth) series magnesium alloys are enclosed, as well as the effects of casting processes. The plasticity enhancement of as-cast magnesium alloys was mainly attributed to the combination of the grain refinement and the second phases introduced by alloying elements, and microalloying with several alloying elements was more favorited. Heat treatment, rapid cooling casting and external electromagnetic field were also beneficial to mechanical properties and worth to be promoted in industrial engineering.
