In this study, the spherical Ti-Al-4V powders were produced by argon gas atomization using a water-cooled copper crucible. The microstructures of gas-atomized powders with various particle sizes were also investigated in terms of either surface or cross-sectional areas using a scanning electron microscope and a transmission electron microscope. The results show that the surface of coarse powders exhibited cellular structure with equiaxed grains. However, the fine powders achieved smooth surfaces without any crystallization observation. Attributed to rapid solidification, both α cells and acicular martensite α’ phases were observed in the internal area of coarse powders, while only honeycomb cellular structure was demonstrated with refined grains in fine powders.
