The TC4 of hot rolling titanium alloy sheet of 10 mm thickness was taken as the raw material in this paper. The plastic behavior of titanium alloy sheet at the high strain rate was studied and analyzed through the Hopkinson compressive bar and forced shear experiments. The material true stress strain curves of different heat treatment mechanisms were obtained. At last the microstructures of tested materials with different heat treatment mechanisms were also observed.
