Abstract The effects of hot isostatic pressing(HIP) treatment at different temperatures on the microstructure and mechanical properties of electron beam selective melting(EBSM)-fabricated Ti6Al4V components were investigated. The results demonstrate that HIP treatment at 800 ℃ significantly reduces the defects while improving hardness and strength. Specifically, the ultimate tensile strength increases from 826.2 MPa to 850.2 MPa, yield strength rises from 729.1 MPa to 758.5 MPa, and elongation after fracture improves from 10.97% to 11.57%. The Vickers hardness also increases from 306.9HV to 333.1HV. When the HIP temperature is elevated to 920 ℃, the component exhibits an ultimate tensile strength of 834.2 MPa, yield strength of 737.5 MPa, and Vickers hardness of 401.5HV, with elongation after fracture substantially increasing to 14.57%. Microstructural analysis revealed that higher HIP temperatures promote the transformation of Widmanstatten structure to basket-weave morphology, accompanied by a gradual decrease in α-phase content and corresponding increase in β-phase fraction. Additionally, grain growth is observed along with reduced dislocation density and lower proportions of low-angle orientation grain boundaries.
