Abstract:
Along with the urgent need of higher performance light quality magnesium alloys for energysaving and carbon emission reduction in automobile and other industries of late years, magnesium alloys exhibit much development prospect in industry application. Rare earth magnesium alloy series have been attached more and more importance owing to their highperformances, including high strength at high temperature, excellent creep resistance & heat resistance, and good plasticity and corrosion resistance, etc. They have been widely used in fields such as aerospace, electronics, automobile, communication, and so on. At present, a series of rare earth magnesium alloys, including Mg Gd, Mg Y, Mg Gd Y, Mg Y Gd, and etc., have been developed worldwide. Current research development and application status of advanced Mg alloys were reviewed, mainly on new development of binary and complex MgY and MgGd alloys, as well as on status of Mg Y Zn, Mg Gd Zn, Mg Gd Y Zn and Mg Y Gd Zn alloy series with long period stacking ordered structures. At last, the development trend of advanced Mg alloy was proposed.
