Microstructures and Mechanical Properties of the Mg-xGd-Er (x=5, 7, 9 and 11wt%) Alloys

Abstract:

In this paper microstructures and mechanical properties of the Mg-xGd-Er (x=5, 7, 9 and 11wt.%) alloys were characterized and discussed. The results show that the alloys with different Gd were mainly composed of α-Mg solid solution, semi-continuous network-like secondary phases of Mg5Gd and cuboid-shaped compound of Mg(GdEr). The ensile strength and yield strength increase as the content of Gd increase. This improved mechanical properties are mainly ascribed to the formation of network-like secondary phases of Mg5Gd.
