Abstract

The flow stress behaviour of Ti-5553 titanium alloy during hot compression deformation was studied by thermal simulation test at the deformation temperature of 750-900°C and the strain rate of 0·001-0·1 s^-1 on the Gleeble-3500 thermal and mechanical simulator. The results show that the flow stress was controlled by both strain rate and deformation temperature. The flow stress decreased with the increasing deformation temperature, and increased with the increasing strain rate until the flow stress reached the peak value, then the flow stress remained constant. The flow behaviours were described by hyperbolic sine constitutive equation, and the average activation energy was calculated. Meanwhile the dynamic recrystallisation phenomenon has been observed during hot deformation.
