Abstract

The hot deformation behavior of Ti-43Al-4Nb-1Mo-0.1B alloy was investigated at the temperatures from 1000°C to 1200°C and strain rates from 0.001s-1 to 1s-1on Gleeble-1500 thermo-simulation machine with true strain of 0. 8. The results indicated that the flow stress decreases with the increase of deformation temperature at a constant strain rate, and increases with the increase of strain rate at constant temperature. Using the linear regression analysis method, the hot deformation constitutive equation based on hyperbolic sine form model was obtained. The microstructure evolution during the hot compression process was investigated, and the effect of beta phase on the hot deformation behavior of TiAl alloy was studied as well.
