Abstract

Abstract

The Ti-25Ta alloy powder was successfully prepared by radio frequency plasma spheroidization, and the Ti-25Ta alloy spherical powder was subsequently formed by selective laser melting. The effect of laser power on the surface morphology, density, microstructure and mechanical properties was studied. The results show that the D₅₀ of the Ti-25Ta alloy powder after spheroidization is 43.8 μm, which is slightly larger than that of the raw material. The interior of the raw material powder exhibits dendrite structure, while the interior of the powder after spheroidization shows a cellular structure. The flowability, bulk density and tap density of the powder are greatly improved. As the laser power increases, the α′ martensite refinement is obvious. At a higher laser power of 200 W, the density reaches a maximum of 95.32% vs. solid, and the microhardness (HV_0.3) is 378.2. The tensile testing shows that with the increase in laser power, the fracture mechanism of the material changes from brittle fracture to brittle-ductile fracture.
