【 摘 要 】

TC4 (Ti-6Al-4V) powder prepared by electrode induction melting gas atomization (EIGA) was used as raw material and SEM was used. The morphology, microstructure, particle size, distribution and phase composition of the powder were characterized by laser particle size analyzer and X-ray diffraction analyzer. At the same time, the influence of the powder properties of TC4 alloy for 3D printing was studied. The results showed that the powder prepared by EIGA was mainly spherical with good fluidity. The main particle size distribution of the powder is in the range of 50 ∼ 180 μ m, which meets the requirement of laser 3D printing. When the pressure is 6.0MPa, the loose density of powder is 2.96g/cm3, and the fluidity is 2.24g/s. Staggered acicular martensite α'-phase composition.
