Effect of Cold Rolling Level on Recrystallization Textures in Low Carbon Steel Sheets - Modelling

Texture evolution during continuous annealing of an interstitial-free steel, cold rolled at five different levels between 55% and 90%, is studied. In order to compare with the more usual 75-80% cold rolled levels, local orientation as well as misorientation measurements is carried out on the 90% cold rolled and annealed steel. The results show the importance of the oriented nucleation mechanism, which appears to be strongly related to local differences of the dislocation structure in the deformed grains.
