Abstract
In this study, microstructure and texture evolution of TB8 titanium alloys during hot deformation were investigated by using electron back-scattered diffraction (EBSD) analysis. The results showed that dynamic recrystallization (DRX) behavior of TB8 titanium alloys was drastically sensitive to the strain. As the true strain raised from 0.2 to 0.8, the degree of DRX gradually increased. The nucleation mechanism of recrystallization was observed, including discontinuous dynamic recrystallization (DDRX) resulting from the bulging of original boundaries. Furthermore, continuous dynamic recrystallization (CDRX) occurred because of the transformation of low-angle grain boundaries (LAGBs) to high-angle grain boundaries (HAGBs) in the interior of the original deformed grains. The texture evolution of TB8 titanium alloy during hot deformation process was analyzed in detail, and five texture components were observed, including {001}\(\left\langle { 100} \right\rangle\), {011}\(\left\langle { 100} \right\rangle\), {112}\(\left\langle { 1 10} \right\rangle\), {111}\(\left\langle { 1 10} \right\rangle\), and {111}\(\left\langle { 1 1 2} \right\rangle\). As the true strain increased, deformation textures were gradually weakened due to an increase in the volume fraction of DRX grains. When the true strain was 0.8, the main texture components consisted of the recrystallization texture components of the {001}\(\left\langle { 100} \right\rangle\) and {011}\(\left\langle { 100} \right\rangle\) textures.
