Texture evolution of commercial pure Ti during cold rolling and recrystallization annealing

X-ray diffraction (XRD) was employed to analyze the texture evolution of commercial pure (CP) Ti during cold rolling and recrystallization annealing. The texture components were measured by electron backscattered diffraction (EBSD) after recrystallization annealing. The CP Ti tends to form a texture with the basal pole tilted 30°?C40° away from the normal direction toward the transverse direction. The texture of the initial hot-rolled plate can be classified into three kinds, i.e., the pyramid texture $\left( {\bar 1013} \right)\left {5\bar 2\bar 30} \right]$ and $\left( {\bar 2021} \right)\left {10\bar 15} \right]$ , the basal plane texture $\left( {0001} \right)\left {2\bar 1\bar 10} \right]$ , and the stronger prism texture $\left( {11\bar 20} \right)\left {0001} \right]$ . After cold rolling and annealing (700°C, 60 min), the main texture components are the cold-rolled texture $\left( {11\bar 25} \right)\left {11\bar 23} \right]$ and the recrystallized texture $\left( {\bar 1013} \right)\left {5\bar 2\bar 30} \right]$ . The texture $\left( {\bar 2021} \right)\left {10\bar 15} \right]$ is inherited from the texture of the initial hot-rolled plate with the decrease of orientation density gradually. The volume contents of the cold-rolled texture $\left\{ {\bar 2115} \right\}\left\langle {01\bar 10} \right\rangle$ and the recrystallized texture $\left\{ {10\bar 13} \right\}\left\langle {1\bar 210} \right\rangle$ are calculated by EBSD. After recrystallization annealing, the specimen is rich in the recrystallized texture and inherits some of texture components from the cold-rolled texture. When the annealing time is prolonged, the anisotropic value decreases.
