Abstract:Sr is a very potential alloying and/or micro-alloying element for magnesium alloys. The investigations about the effects of Sr addition on the microstructure and properties of magnesium alloys and the development of new type Sr-containing magnesium alloys have attracted an increasing interest. Recently, the work was focused on the grain refinement and the improvement of second phases in magnesium alloys by addition of strontium. The latest research status about the effects of Sr addition on the microstructure of magnesium alloys and the development of new type magnesium alloys containing Sr were reviewed, and the existing problems were discussed. The research work shows that the microstructure and composition of the master alloys containing Sr have obvious influence on the grain refinement of magnesium alloys caused by addition of strontium.
