X-ray diffraction (XRD) was employed to analyze the texture evolution of commercial pure (CP) Ti during cold rolling and re-crystallization annealing. The texture components were measured by electron backscattered diffraction (EBSD) after recrystallization an-nealing. The CP Ti tends to form a texture with the basal pole tilted 30°-40° 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 and , the basal plane texture , and the stronger prism texture . After cold rolling and annealing (700°C, 60 min), the main texture components are the cold-rolled texture and the recrystallized texture . The texture is in-herited from the texture of the initial hot-rolled plate with the decrease of orientation density gradually. The volume contents of the cold-rolled texture and the recrystallized texture 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.
