Abstract

The evolution of texture due to recrystallization was investigated in cold rolled Ti-bearing IF steel sheets using Electron Back Scattering Pattern (EBSP). The aim of this study was to obtain a real picture of the formation of the recrystallization texture of IF steel sheets, which would contribute to proper texture control for improving deep drawability. The deformed grains can be roughly classified by the following 5 orientation groups: (1) ND//〈111〉 and RD//〈112〉∼〈110〉, (2) ND//〈111〉∼〈335〉 and RD//〈110〉, (3) around {112}〈110〉, (4) around {001}〈110〉 and (5) widely scattered orientations. Their ratios of frequency of finding are approximately 12:4:4:5:2. Deformed grains of types (1) and (5) recrystallized at the early stage of recrystallization. The nucleation sites are both grain boundaries and grain interior. The orientations of grains recrystallized from a grain of type (1) are ND//〈111〉 and RD//〈112〉∼〈110〈 while the orientations of grains recrystallized from a grain of type (5) are widely scattered. Most of the deformed grains of types (2), (3) and (4) recrystallized at the later stage of recrystallization. The recrystallization of these grains of types progresses through the growth of already recrystallized neighboring grains if the neighboring grains are types (1) and (5). There exist no preferential misorieritation axes for migrating recrystallization fronts. Most of the misorientation angles lie between 20° and 55°.
