Present Development Status of Anti-creep Heat Resistant Magnesium Alloys

The mechanism of creep resistance at elevated temperatures of magnesium alloys and the method to improve the resistance of the alloys are discussed with the present status of the researches of the heat resistant cast alloys(Mg-Al,Mg-Zn,and Mg-RE) highlighted.Some thoughts about the development trend of the alloys with excellent properties are described.It is concluded that in order to solve the problems existing with the heat and creep resistance of the cast alloys,the alloying elements must be optimized.
