| Abstract: | At present the as-cast grain refinement technologies of magnesium alloys consist of the melt superheating treatment,Elfinal process,carbon inoculation,melt agitation method,Zr,Ca,Sr and other alloy elements addition method chiefly. In this paper,the research status and development of these as-cast grain refinement technologies of magnesium alloys were reviewed,and the processing characteric and refinement mechanism of these different refinement methods were analyzed emphatically,and the existing problems and development direction were pointed out. |
