Abstract
The flow stress behavior of TB6 titanium alloy during hot compression deformation was studied by thermal simulation at deformation temperature from 700℃to 860℃and the strain rate from 0.001 s~(-1) to 1 s~(-1).The influence of temperature,strain rate and strain rate on the flow stress behavior during hot deformation was described,and the constitutive equation of the plastic deformation of TB6 alloy was obtained.The results show that the flow stress increases with the increase of strain and tends to be constant after a peak value.The peak stress increases with the increase of strain rate,and tends to decrease with the increase of deformation temperature.
