properties of alloys are consistent with the grain sizes. 0.26% (mass fraction) of CaC2 addition reduces the mean grain size of pure magnesium from more than 2 mm to 125 μm, and the ultimate tensile strength... suspension particulates has a significant influence on the strength properties of pure Mg. The tensile strength decreases with increasing CaC2 addition, and it consists of the change of grain size......

The strength yields at the highest strain... microstructures and thus mechanical performance including the strength and plasticity of the bulk material. On the one hand, the increase of tensile temperature brings down the yield strength......
and compressive creep resistance The tensile properties of the four as-cast alloys were examined. The results are shown in Fig.5. The tensile test results indicate that the tensile strength and elongation of these alloys increase with increasing Sn addition. The optimum mechanical results are attained in Mg-8.5%Sn-2%La alloy, where the ultimate tensile strength is about 140 MPa and the elongation is 13......
