Abstract: The microstructure, mechanical properties and creep behavior of Mg-Gd-Y-Zr alloys at different temperatures and stresses have been investigated. Results show that the tensile properties and creep resistance at T6 condition is much higher than that at as-cast condition. The creep resistance of Mg-Gd-Y-Zr alloy at 250°C/80MPa is markedly better than that at 300°C/50MPa, indicating that temperature makes more effects on the creep resistance than the stress.

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.
