Abstract: Aging strengthening has the advantages of simple, effective and easy to industrialize, which has been widely used to enhance the mechanical properties of magnesium alloys. The research progress of aging strengthening Mg-Zn-（Zr）,Mg-Al, Mg-Sn and Mg-RE alloys was reviewed. The effects of aging precipitation on the microstructure and mechanical properties of magnesium alloys were introduced. The existing problems were analyzed, and the future research of aging strengthened magnesium alloy was prospected.
