摘要
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 （1013）[5230] and （2021）[1015], the basal plane texture （0001）[2110], and the stronger_prism_texture （1120）[0001]. After cold rolling and annealing （700℃,60 min）,_the main texture components are the cold-rolled texture （1125）[1123] and the recrystallized texture （1013）[5230]. The texture （2021）[1015] 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 {2115}（0110） and the recrystallized texture {1013}（1210） 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.
