Abstract

Abstract

A comparative and systematic study was conducted on the effects of annealing temperatures on the microstructure and texture of cold-rolled pure titanium plates using testing methods and analysis methods such as Electron Backscatter Diffraction (EBSD). The results show that when the intermediate annealing temperature is 700 ℃, the recrystallized structure of 0.25 mm plate obtained by cold rolling from 0.6 mm plate and 700 ℃/h treatment is more uniform with smaller residual stress. The textures on the {0001}, {10-10}and {11-20} three pole figures are more scattered with weaker overall texture intensity, and the orientation distribution is more random.
