Effects of Cold Rolling Reduction on Properties and Textures of IF Steel Containing Nb and Ti after Annealing

  • The industrial produced hot-rolled IF steel sheet containing Nb and Ti was cold rolled with different cold rolling reductions, and then, the cold rolled steel sheet was annealed in a pre-vacuum-pumping protection atmosphere annealing furnace. The annealing temperature and time were 720 ℃ and 5 h, respectively. The properties and textures of the as-annealed steel sheet were tested. The results show that good combination of mechanical properties could be obtained when the cold colling reduction was 70%-90%, and the cold colling reduction had little effect on the properties of the annealed steel sheet. With the cold rolled reduction increasing, the recrystallized grains were refined, and the intensity of the {001}〈110〉 and {112}〈110〉 cold rolled textures increased, which would provide sites for the {111} textures annexation during annealing and made the {111} recrystallized textures stronger. However, the stability of the {114}〈110〉 and {223}〈110〉 cold rolled textures were high, these textures were remained after recrystallization annealing.
