Microstructural and textural evolution by continuous cyclic bending (CCB) and annealing in a high purity titanium sheet has been investigated. The hardness distribution through thickness in the CCBent sheet exhibits V-shape with marked difference between the surface and the inside. More deformation twins are observed in the surface of the sheet subjected by more CCB passes. After annealing, the texture in the sheet which was CCBent in rolling direction is randomized, while the as-received sheet has typical textural components in rolling and recrystallization of the rolled titanium sheet. On the other hand, in the CCBent sheet in transverse direction, development of the rolling texture component is found after annealing. Further, the textural evolution is compared with that in a commercial purity titanium.
