Abstract：

In the isothermal forging processing of TC4 titanium alloys, a criterion deciding the plastic state of material was put forward. Strain rate sensitive index was calculated through the experimental data with the orthogonal test. In order to judge the plastic state conveniently, the contour lines of strain rate sensitive index was obtained under different strains. The simulated results indicate that there are different plastic deformation mechanisms in the deformation processing. It is evident that multiple plastic deformation mechanism is correct and the transformations of different mechanisms occur during the processing of deformation.
