Influence of α region hot rolling on the rolling and recrystallization texture of cold rolled Ti-bearing extra low carbon steel sheets

To realize a remarkable improvement of the deep drawability of steel sheets, the formation of texture of Ti-bearing IF(Interstitial atoms free) steel sheets has been investigated throughout the rolling and annealing processes. The textures formed by rolling and annealing has been studied at the surface and the midplane of IF steel sheets. The formation of the recrystallization texture has been discussed taking into consideration of the stored energy and the crystal rotation relationship around the axes between the orientation of the recrystallized grain and the surrounding deformed matrix. The obtained results led to the conclusion that the α-region hot rolling under certain conditions is a very effective means of improving the deep drawability of IF steel sheets.
