摘要：
Mg-Gd-Nd alloys have good development prospects. The introduction of alloying elements Zn, Y, Zr and equal channel angular pressing (ECAP) can further improve the microstructure and mechanical properties of the alloys. In this paper, the principle of composition design and equal channel angular pressing (ECAP) technology of high strength and heat resistant magnesium alloy are summarized. The research progress of microstructure and aging precipitation behavior of Mg-Gd-Nd alloy, the evolution law of microstructure and mechanical properties of magnesium alloy during ECAP are introduced. The shortcomings of Mg-Gd-Nd alloy and equal channel angular pressing process in production and application are pointed out. © 2021, Editorial Office of Journal of the Chinese Society of Rare Earths.
