Effect of Cold-rolling Reduction on Recrystallized Annealing Microstructure and Texture of Titanium Stabilized Interstitial Free Steel

Cold rolling and salt bath annealing simulation were conducted to study the evolution of microstructure and textures of a commercially produced Titanium stabilized interstitial free steel by means of optical microscopy and X-ray texture measurement. The results show that all of the as cold-rolled specimens are completely recrystallized after annealing. As the cold-rolling reduction increases, the recystallized ferrite grains are refined, The intensities of the stable {114}< 110 > and {223}< 110 > components remain strong after recrystallization. The orientation intensity of the {111}< 110 > and {111}< 112 > also increases accordingly. As the cold-rolling reduction increases to 90%, the intensity of {111}< 112 > tend to be higher than that of {111}< 110 >.
