Abstract
The textures for cold-rolled and annealed commercially pure titanium may have never been reported, for all the informations on iodide titanium. Here preferred orientations developed in this material are, in detail, investigated and are compared with the results already shown. The experimental results obtained in five specimens having different reductions are a little differnt from those in iodide titanium, as follows: (1) Cold-rolled texture is such shown 25∼30° rotated {0002}⟨10\bar10⟩ texture about the axis of rolling direction. In the basal plane pole figure, there develops the texture like that from compression, spread approximately 15° and 25∼30° about the rolling and the cross direction respectively. These textures are mainly explained by the twinned orientations of the first order. (2) Annealing texture at less than 600° retains the cold-rolled texture, and at 700° shows a component explained by the cold-rolled and recrystalized one already noticed in the cold-rolled. Recrystalized texture is shown by aproximately 25° rotation of {0002}⟨11\bar20⟩ texture about the axis bfore mentioned and is clearly described by a 30° rotation about the ⟨0002⟩ direction held with cold-rolled texture. Recrystalized and its basal plane double texture become more pronounced the higher the reduction and the annealing temperature. The recrystalized texture is the same as the high temperature anneled, even after the transformation.
