Abstract
In this study, we fabricated spherical Ti-6Al-4V powders using gas atomization. Scanning electron microscope, optical microscope, X-ray diffraction and particle size distribution were extensively performed to investigate the properties of gas-atomized Ti-6Al-4V powders. The XRD analysis shows all the gas-atomized powders are with both α and β phases. The surface of coarse powders exhibited cellular structure with equiaxed grains. However, the fine powders achieved smooth surfaces and could not be observed any crystallization. Attributed to rapid solidification, both α cell and needle-like martensite α’ phase were observed in the internal area of coarse powders, while only honeycomb cellular structure was demonstrated with refined grains in fine powders.
