| Abstract: | The research development and elevated temperature creep mechanism of magnesium alloys were discussed in this paper. The current research and application status of the creep resistant magnesium alloys used for high pressure die casting and for gravity casting in automobile were reviewed. The current creep resistant magnesium alloys used in automobile power train have also existed lots of disadvantages, such as the poor combination property, complex production technology, and the high cost of production. It is considered that exploiting the alloy with excellent casting, good creep resistance, high performance-price ratio is the future development direction. |
