Along with the research and development of heat-resistant magnesium alloy more deeply in recent years, it is applied in the fields of manufacturing automobiles, aerocrafts and so on, and it’s more and more irreplaceable.

The progress of the research of heat resistant magnesium alloys in China is reviewed in this paper with the effect of the alloying elements including RE,Si,Ca and Sr on the high temperature properties of the alloys and their strengthening mechanism described.

The current research status and application of heat resistant magnesium alloy were introduced,and strengthening mechanism and the effect of alloying element,including RE,Si,Ca,Sr,on the high temperature properties of magnesium alloy were reviewed.

The microstructure,mechanical and tribological properties of heat resistant magnesium alloy containing rare earth under room temperature and 150 ℃ were studied,the wear mechanism of magnesium alloy under 150 ℃ was discussed.

Finally,some summaries in application and the future research direction of heat resistant magnesium alloys are put forward.
