Abstract

Heat treatments in the temperature range of 800~950℃for 10~60 min was applied to water-quenched Ti65 alloy, in order to investigate the martensite decomposition and its effect on tensile properties at room temperature. The results show that detectable martensite decomposition is already found at 800℃ with a holding time of only 10 min. The martensite decomposition occurs through the diffusion of β-stabilizing elements from the interior of α' plate to the interface to form β phase. The morphology of the β phase changes from irregular to regular rods of varied aspect ratio with prolonged holding time. Increasing temperature leads to apparent coarsening of the decomposition products. Both room-temperature tensile and yield strengths decrease after the heat treatments. Nearly constant strength was found for the heat treatments in the range from 800℃/40 min across 850℃ 20 min/40 min/60 min to 900℃/20 min. The decrease of strength is attributed mainly to the weakened solution strengthening induced by the decomposition of martensite phase. After the completion of the decomposition of the martensite phase, the strength remains almost constant due to the balance between the weakening induced by the coarsening of α plate and the strengthening by the dispersed α₂ particles.
