The high-quality deposited samples with no metallurgical defects were investigated by laser direct deposition to research the effects of solution temperature (910-970 ℃) and aging temperature (500-600 ℃) on the phase composition, microstructure, and tensile properties of the deposited samples. The result shows that the alloy microstructure of the as-deposited and solution-aging samples contain a large amount of α-Ti (α) phase and a small amount of β-Ti (β) phase. In addition, as solution and aging temperatures increase, the α-Ti (α) phase of microstructure changes from the acicular to the short rod-like. For the tensile properties, there is a higher tensile strength index in the solution aging state (940 ℃/1 h/WQ+550 ℃/4 h/AC, 970 ℃/1 h/WQ+550 ℃/4 h/AC, 940℃/1 h/WQ+600 ℃/4 h/AC) than the national standard requirements (σb≥895 MPa, σ0.2≥828 MPa, δ≥10%) for forgings. The fracture morphology is plastic.
