Abstract：
The research progress of Cu-Zr based amorphous alloys at home and abroad in recent years was summarized.The effects of rare earth elements Y, Gd and Sc on Cu-Zr based amorphous alloys were analyzed, including purifying melting, deoxidizing, improving glass forming ability and mechanical properties. The mechanism and application of rare earth elements in the system of Cu-Zr base amorphous alloy are expounded. By analyzing the physical and chemical characteristics of rare earth elements, the reasonable selection of rare earth elements can improve the performance of Cu-Zr base amorphous alloy.
