Influence of Heat Treatment on the Microstructures and Properties of Mg-12Li-3Gd-3Y-0.6Zr Alloy

Abstract:

A new kind of Mg-12Li-3Gd-3Y-0.6Zr alloys was prepared in vacuum conditions with the protection of argon atmosphere. The effects of heat treatment on the microstructure and mechanical properties of Mg-12Li-3Gd-3Y-0.6Zr alloy were studied by optical microscopy, SEM, XRD and tensile test. The results show that the highest tensile strength of the alloy reaches 142MPa after aging treatment at 373K for 2h, and the best elongation of the alloy reaches 54% after solid solution and aging treatment at 673K for 2h + 373K for 2h. The X-ray analysis of the investigated alloy shows that the phase structure of the investigated alloy is β-Li, Mg₂Gd and Mg₂₄Y₅.
