Firstly,this article briefly introduces the applications of high strength aluminum alloys in aviation and rail transit.The evolution of aviation aluminum alloys using micro-alloying method is then retrospected.The effect of micro alloying elements on the properties of the high strength aluminum alloy is subsequently reviewed.Finally,based on the characteristics of rail transit area,the comprehensive consideration of weld-ability and corrosion resistance of micro-alloying alloys should be underlined and corresponding systematic research should be required for the high strength aluminum alloys in rail transit.
