Using Spark Plasma Sintering process (SPS), consolidation behavior of gas atomized alloys were investigated via examining the microstructure and evaluating the mechanical properties. In the atomized ahoy powders, fine particles were homogeneously distributed in the matrix. The phase distribution was maintained even after SPS at 723 K, although particles were newly precipitated by consolidating at 748 K. The density of the consolidated bulk Mg-Zn-Y alloy was . The ultimate tensile strength (UTS) and elongation were varied with the consolidation temperature.
