Microstructure and Mechanical Properties of Mg-12Gd-2Y-2Sm-0.5Zr Alloy

Abstract:

The Mg-12Gd-2Y-2Sm-0.5Zr (wt.%) alloy was prepared by induction melting. After solution and aging treatment, the microstructure and mechanical properties of alloy was investigated by optical microscope, XRD and tensile tests. The results show that the aged alloy is mainly composed by α-Mg matrix, Mg₂₄Y₅ and Mg₅Gd phase, and these precipitated phases distribute in the grain dispersively. The mechanical properties of alloy were tested at room temperature and 200-300°C.
