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.
