Research and Development of Mg-Al-Sr Alloys
The addition of strontium to Mg-Al based alloys offers good creep resistance to meet the material requirements for automotive applications. The composition, microstructure and mechanical properties of Mg-Al-Sr alloys are discussed in this paper. The effects of alloy elements such as Ca, Ti and Mn in Mg-Al-Sr alloy are summarized. Technologies for preparation of Mg-Sr master alloy were developed, including mixture method and vacuum thermal reduction method which may also be used for preparation of Mg-Al-Sr alloys.
