Development of Texture and Grain Boundary Character in a Boron Bearing IF Steel after Recrystallization Annealing

The development of texture and grain boundary character are researched for a boron bearing IF steel after recrystallization annealing for different times at 810 degrees C. The results show that the main texture components are {111}< 110 > and {111}< 112 > after the cold rolling samples annealing different times. The maximal volume fraction of < 111 >//ND texture is about 78% for the sample annealing for 120sec. The main CSL boundaries are Sigma 3, Sigma 5, Sigma 7, Sigma 9, Sigma 11, Sigma 13b and Sigma 17b. And the Sigma 3 grain boundary increase with increasing the annealing times from 60sec to 180sec.
