Commercial pure (CP) titanium plates were rolled at various of temperatures at 25℃,150℃,300℃and 450℃with a reduction of 30%. After pickling and annealing for 1 hour at different temperatures above and below that of recrystallization, specimens were characterized using Vickers hardness testing, optical microscopy and electron back-scattered diffraction (EBSD).Optical microscopy characterization provided evidence of the microstructure evolution in all the samples. Most of the grains were elongated or broke up after rolling. Interestingly, material rolled at higher temperature gave much more heterogeneous microstructure which led to faster recrystallization in subsequent annealing.EBSD technique showed the detailed grain orientation information and texture of the samples. Warm rolling produced greater orientation gradients and more heterogeneous deformation microstructure than cold rolling and the texture was strengthened by higher rolling temperature. Thus, the start of recrystallization is faster after warm rolling due to higher nucleation rate; recrystallization was promoted in spite of the decrease of stored energy consumed by dynamic recovery.
