| Abstract: | This paper reviews the current research development and application status of elevated temperature magnesium alloys and summarizes various new magnesium alloys containing alkaline earth elements that have been developed in recent years for elevated temperature applications. The effects of alkaline earth elements Sr and Ca on the castabilities, microstructures, mechanical properties and tensile creep resistance of Mg-Al based magnesium alloys are analyzed and discussed. The potential applications of these alloys in automotive industry are also pointed out. |
