High strength magnesium alloy parts with big sizes are significant to enhance the large scale applica鄄
tion of magnesium alloys. At present, the research and development on high strength magnesium alloys have received
much attention all over the world,and consequently many researches have been carried out. In this paper, the latest
research and development status of conventional high strength magnesium alloys, especially the research on high
strength magnesium alloys containing RE elements, novel plastic deformation craft and magnesium alloy parts with big
sizes, are reviewed, and the existing problem and research tendency are also analyzed and pointed out respectively.
