Abstract
Microstructure and mechanical properties of a metastable β titanium alloy were investigated in different heat treatment conditions. The alloy was melted by consumable vacuum arc melting followed by conventional forging and rolling. Microstructure and mechanical property evaluation were carried out in solution treatment and three different aging conditions. While low temperature aging resulted in increase in strength and decrease in ductility as compared to solution treatment condition, a double aging cycle provided considerably higher elongation values with a marginal increase in strength. Maximum fracture toughness was obtained in the double aging condition.
