Abstract

Using Spark Plasma Sintering process (SPS), consolidation behavior of gas atomized Mg97Zn1Y2 alloys were investigated via examining the microstructure and evaluating the mechanical properties. In the atomized alloy powders, fine Mg12YZn particles were homogeneously distributed in the α-Mg matrix. The phase distribution was maintained even after SPS at 723 K, although Mg24Y5 particles were newly precipitated by consolidating at 748 K. The density of the consolidated bulk Mg-Zn-Y alloy was 1.86g/㎤. The ultimate tensile strength (UTS) and elongation were varied with the consolidation temperature.
