Microstructure and Mechanical Properties of Mg-Gd-Sm-Zr Alloy

Abstract:

Microstructure and mechanical properties of three kinds of Mg-Gd-Sm-Zr alloys have been analyzed in this paper. Results exhibit that the microstructure of as-cast Mg-Gd-Sm-Zr alloy contains α-Mg and eutectic compounds which are mainly comprised of most Mg5Gd-base phases and a few Mg41Sm5-base phases by EDX and XRD analysis. Ultimate tensile strength and yield strength of the alloys can be significantly improved after T6 treatment. Mechanical properties of studied alloys in T6 condition are better than that of WE54-T6 alloy.
