The reason for obtaining such high share of ¦Ã-fiber texture is mainly due to large cold rolling deformation and full response to deformed microstructure. As the extending of holding time, the texture intensity gradually increase while the texture types of sample remain roughly unchanged. Compared with sample under direct annealing, sample under such heat-treatment mechanism has higher ¦Ã-fiber texture and less {211}<011> texture. However, both annealing mechanisms can hardly remove {100}<011> rotating cube texture grain of lower deformation stored energy. |
