Abstract: TA1 pure titanium sheets were prepared by corrugated roll + flat roll rolling (CFR) and flat roll + flat roll rolling (FFR)at 400℃.The microstructure and texture evolution characteristics of TA1 pure titanium sheet after annealing at 650 ℃for 1 h were analyzed by SEM and EBSD techniques.The results show that after corrugated roll rolling, the change of periodic microstructure is exhibited in the RD direction, and progressive microstructure gradients are exhibited in the ND direction. After the second pass of flat rolling, the samples were annealed at 650℃for 1 h, and the equiaxing degree of the CFR titanium sheet is lower than that of the FFR titanium sheet.After the pole figure analysis of the two processes, it is found that the texture of the titanium sheet prepared by the two rolling processes is a typical basal plane bimodal TD texture, and the texture in the middle region of the CFR titanium sheet in the thickness direction is weakened in a certain extent, and the extreme density regions in the TD axis direction are numerous and dispersed.In addition, the texture types of titanium sheets prepared by the two rolling processes are similar.
