摘要：
In this paper, the microstructure evolution of TC17 titanium alloy formed by laser solid forming were analyzed, and the influence of solution and two-stage aging heat treatment on the microstructure homogenization and room temperature tensile properties were investigated. The extension of heat treatment temperature and time will lead to the size and volume fraction of primary lath α phase increasing, but decreasing for secondary α phase. Aging has no effect on the change of grain morphology but leading to the primary α lath coarsening. The hardness is the lowest at the secondary solution temperature of 750 °C. The strength and plasticity of heat-treated samples suffering 920 °C/0.5 h/ water quenching + 750 °C/1 h/water quenching + 630 °C/4 h/air cooling match well. The anisotropy is basically eliminated at the secondary solution temperature of 830 °C.
