In order to improve the understanding of the dynamic recrystallization (DRX) behaviors of TA15 titanium alloy (Ti-6Al-2Zr-1Mo-1V), a series of experiments were conducted on a TMTS thermal simulator at temperatures of 1173 K, 1203 K, 1223 K, and 1273 K with the strain rates of 0.005 s−1, 0.05 s−1, 0.5 s−1, and 1 s−1. By the regression analysis for conventional hyperbolic sine equation, the activation energy of DRX inα+βtwo-phase region isQS=588.7 Kg/moland inβregion isQD=225.8 Kg/mol, and a dimensionless parameter controlling the stored energy was determined asZ/A=ε˙exp(588.7×103)/RT/6.69×1026inα+βtwo-phase region and asZ/A=ε˙exp(225.8×103)/RT/5.13×1011inβregion. The DRX behaviors of TA15 titanium alloy were proposed on the strength of the experiment results. Finally, the theoretical prediction results of DRX volume fraction were shown to be in agreement with experimental observations.

X-ray diffraction and EBSD techniques were applied to investigate microstructure evolution and phase transition of thermal deformed TA15 titanium alloy under different heating methods(β phase zone heating and conventional heating). The results indicate that microstructures of thermal deformed TA15 titanium alloy after water quenching appear grain refinement undergoing these two kinds of heating methods. A large number of primary equiaxed α grains are retained after two phase zone deformation under conventional heating method. Meanwhile more regular arrangement and greater cluster of acicular plate martensite microstructure and clear original β grains are obtained through β phase deformation and water quenching. The diffraction peak of (200) crystal face of Al-rich α phase disappears under β phase zone heating method. The preferential orientation of TA15 titanium alloy after thermal deformation and water quenching is reduced obviously under β phase zone heating method.
