Abstract

The characteristics of alkaline earth element Sr was described.The progress in effects of Sr on microstructures and heat resistance of magnesium alloy were reviewed.Through adding Sr

heat resistance of magnesium alloy was improved

and mechanical properties of the alloy were increased as a result of refining grain size.In addition

the problems of the magnesium with Sr were presented

such as refining mechanism

interaction with other alloying element as well as smelting and preparation of alloy

and the development trend was prospected.
