The results show that Y can refine the microstructure of α-Mg phase, improve its shape, and decrease, even eliminate the α-Mg phase by forming γ(Mg24Y5)phase with Mg; the γ phase changes from dispersed into network state with the increase of the Y content. Meanwhile Y enhances the tensile strength of Mg-8Li alloy, and the optimal comprehensive mechanical properties of the alloy can be obtained when the content of Y is 4%.Read More
