Heat-treatable Mg–Sn–Zn wrought alloy

We report enhanced room-temperature tensile and creep properties of extruded Mg–Sn–Zn alloys by solution heat-treatment and artificial aging. Microstructure observations indicated that the improved creep properties were due to the uniform dispersion of Mg2Sn and MgZn2 phase in the coarse grains. The mechanical properties of the heat-treated extruded alloys are comparable to commercial wrought magnesium alloys, and thus are promising as new heat-treatable wrought alloys.
