Abstract | The effects of Nd addition on the microstructures and mechanical properties at elevated temperatures of a Mg–0.3Zn–0.32Zr alloy were investigated in this study. The grain sizes of Mg–0.3Zn–0.32Zr alloys were decreased from 120 lm to 76 lm and grain morphologies were changed from hexahedron to rosette-like by increasing Nd addition from 0.21% to 2.65%. Both Nd and Zn are fully dissolved into the Mg matrix when Nd addition is less than 0.84% and the as-cast structure consists of only a-Mg. Increasing Nd concentration over 1.62%, intermetalitics Mg12(Nd,Zn) phase confirmed by X-ray diffractometer (XRD) occurs |
