Research status and development trend of high-strength Mg-Gd-Y-Zn-Zr series RE-Mg alloys
The application and development of magnesium alloys have been limited in many fields due to poor plasticity at room temperature and low strength at high temperatures.In recent years,scholars at home and abroad have successively developed high-strength Mg-Gd-Y-Zn-Zr series RE-Mg alloys containing a long-period stacking ordered structure phase,and made in-depth studies on the changes of structure and properties and the mecha-nism during the alloy preparation and processing.The article summarizes the research status and development of high-strength Mg-Gd-Y-Zn-Zr RE-Mg alloys in recent years,discusses the effects of alloy composition,conventional plastic processing technology and heat treat-ment on the structure and properties of the alloys,and prospects for the research direction of the alloys.
