Abstract

Using Spark Plasma Sintering process (SPS), consolidation behavior of gas atomized $Mg_{97}Zn_1Y_2$ alloys were investigated via examining the microstructure and evaluating the mechanical properties. In the atomized ahoy powders, fine $Mg_{12}YZn$ particles were homogeneously distributed in the ${\alpha}-Mg$ matrix. The phase distribution was maintained even after SPS at 723 K, although $Mg_{24}Y_5$ particles were newly precipitated by consolidating at 748 K. The density of the consolidated bulk Mg-Zn-Y alloy was $1.86g/cm^3$. The ultimate tensile strength (UTS) and elongation were varied with the consolidation temperature.
