N2  - In the current work, several heat treatments were carried out below and above the beta transus temperature of the Ti-6Al-4V alloy. The resultant microstructures and their effects on hardness, wear resistance and hot tensile properties of the Ti-6Al-4V alloy were examined. The results showed that solution treatment of Ti-6Al-4V samples followed by water quenching from Ý and Ü/Ý fields raised the alloy hardness from 380 to 575 and 656 HV respectively while no remarkable changes were observed after aging. Hot tensile strength of the as-forged sample increased from 671 to 756 MPa after water quenching from the Ý-phase field, while the air cooling decreased the tensile strength 644 MPa. The fracture mode of the tensile samples was more ductile in case of the solution treated samples compared to the as forged samples. A subsurface layer was formed due to the diffusion of oxygen into the surface at high temperatures. This layer masked the differences of wear behavior of the specimens
