Abstract

The hot deformation behavior of Ti-3Zr-2Sn-3Mo-25Nb (TLM) titanium alloy in the temperature range of 750-850°C and strain rate range of 0.001-1s^-1 has been investigated by hot compressive testing on the Gleeble-3800 thermal and mechanical simulator. The experimental results show that the deformation temperature and the strain rate significantly affect the flow stress of TLM alloy during isothermal deformation. The flow stress increases with the decreasing of deformation temperature and increasing of strain rate. There is no instability domain of processing map at the temperature range from 750 to 850°C and strain rate range from 0.001 to 1s^-1. The most peak efficiency domain appears at around deformation temperature of 850°C and the strain rate of 0.01s^-1 with a peak efficiency of 36%. The mechanism in stability domain is dominated by dynamic recovery and dynamic recrystallization.
