Texture evolution of deep-drawing sheet St15 during recrystallizaiton annealing

Electrical back scatter pattern (EBSP) was used to investigate the texture evolution rule of deep-drawing sheet St15 during recrystallization annealing. When the heating rate is 30℃/h, the recrystallization temperature of deep-drawing sheet St15 is about 560℃, the recrystallization finishing time is nearly 2 h, and the strongest component of the recrystallization texture is {100}<110>. γ fibre texture in St15, especially {111}<112>, strengthens with incresing the annealing temperature. When the holding temperature is 700℃, {111}<110> texture in St15 strengthens with increasing the annealing time, and after holding for 4h{111}<112> texture gradually. When the holding time reaches 13 h, a satisfied annealing texture is achieved.
