摘要：

The effect of evolution of microstructure and texture of commercially pure titanium (TA1) annealed at different temperatures was investigated by X-ray diffraction (XRD), and electron backscattered diffraction (EBSD). The results show that recovery and recrystallization of the cold rolled TA1 titanium sheet occur during the annealing process, and typical TD-split basal texture was formed. When the annealing temperature is below 700℃, the microstructure is characterized by recovery and recrystallization, and recrystallization texture components are presented. The as-rolled texture component is gradually weakened and disappears with the increase of the heat treatment temperature. When the annealing temperature reaches 800℃, the grain growth is dominated by merged-growth and the intensity of (0113) < 21 30 > and (1122) < 1 100 > recrystallized texture component continue to increase. In addition, anisotropy of mechanical properties of TA1 sheet is related to the texture components. Due to pyramid textures (0113) < 21 30 > and (1122) < 1 100 > recrystallization textures, the cylinder <a> slip is respectively easier to be activated and the base <a> slip or pyramidal plane <c+a> slip becomes more difficult to be activated respectively, which leads to greater tensile strength in the TD direction than the RD direction of the sheet. As a result, the anisotropy of mechanical properties of TA1 sheet is caused. © 2019, Central South University Press. All right reserved.
