| Abstract: | Alloying elements addition is an important method to improve alloy property or design new al- loys,and has been widely used to study and develop Mg-Al based elevated temperature magnesium alloys at pre- sent.In this paper,the function of alloying elements such as Al,Zn,Mn,Sb,Bi,Sn,Si,RE,Ca and Sr in Mg-Al based elevated temperature magnesium alloys are reviewed,and the effects of Al and Zn on the structure and property of Mg-Al based elevated temperature magnesium alloys are analyzed emphatically.Finally,the existing problems and development direction about the using of alloying elements are discussed. |
