Abstract
MgZn4.3Y0.7 alloy powders were prepared using an industrial scale gas atomizer,
followed by warm extrusion. The powders were almost spherical in shape. The microstructure of
powders as atomized and bars as extruded was examined as a function of initial powder size
distribution using Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscope
(EDS) and X-ray Diffractometer (XRD). The grain sizes were decreased with extruding as well as
decreasing the initial powder sizes. Both the ultimate strength and elongation were enhanced as the
initial powder sizes were decreased.
