It was found that after cold deformation, the sample remained as a single body-centered cubic β phase structure and had rolling texture, and microstructures were characterized by rolling lines. With increasing cold rolling reduction, the intensity of rolling texture changed from weak to strong, At the reduction of 97%, rolling texture were mainly {223} <110> and {112}<110>. After annealing at 800℃ for five minutes, recrystallization was occurred in the samples, and microstructures were made of a large number of equiaxed recrystal grain. After annealing at 800 ℃ for one hour, the recrystallized grain grew. Texture analysis showed that the annealing can not significantly affect the texture of the lower reduction sample, while the texture intensity of the high reduction sample rose sharply after annealing, and a particularly strong annealing texture {111}<112> appeared in the samples. After annealing at 800 ° C for five minutes, the texture state of the high reduction sample was stabilized, and not changed even annealing time extended to one hour.
