Abstract
Using Spark Plasma Sintering process (SPS), consolidation behavior of gas atomized Mg_97Zn_1Y_2 alloys were investigated via examining the microstructure and evaluating the mechanical properties. In the atomized ahoy powders, fine Mg_12YZn particles were homogeneously distributed in the alpha-Mg matrix. The phase distribution was maintained even after SPS at 723 K, although Mg_24Y_5 particles were newly precipitated by consolidating at 748 K. The density of the consolidated bulk Mg-Zn-Y alloy was 1.86g/cm3. The ultimate tensile strength (UTS) and elongation were varied with the consolidation temperature.
