Abstract

Titanium alloy Ti-3Al-2.5V is cheaper to produce and has the potential of improved ductility and formability compared to the Ti-6Al-4V alloy. Various heat treatments were performed on cylindrical tensile test bars in order to optimize the mechanical properties of Ti-3Al-2.5V. The tensile properties of heat-treated Ti-3Al-2.5V were determined at four annealing temperatures with different quenching methods and five different solution treatments and five different aging treatments for varying hours. The samples were tensile tested. The results indicated that optimum properties of high strength and ductility were reached at 926 °C of solution treatment and 480 °C of aging.
