 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.

Abstract
PDF
- Mg-4.3Zn-0.7Y (at%) alloy powders were prepared using an industrial scale gas atomizer, followed by warm extrusion. The powders were almost spherical in shape. The microstructure of atomized powders and those extruded bars was examined using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscope (EDS) and X-ray Diffractometer (XRD). The grain size of the powders was coarsen as the initial powder size increased. After the extrusion, the grain size became fine due to the severe plastic deformation during the extrusion with the ratio of 10:1. Both the ultimate strength and elongation were enhanced with the decrease of initial particle size.
