Statistical analysis of the development of recrystallization texture in IF steel

Development of recrystallization texture in a IF steel containing 0.002wt% C, 0.06 wt% Ti is investigated by EBSD technique. Strong a-fiber texture, maximum at {112}<110> is developed in cold rolled state, and strong ?-fiber texture which has maximum value at {111}<112> is developed after annealing in salt bath. A technique to set a criterion distinguishing recrystallized grains from deformed grains is suggested. Grains of high orientation consistency are regarded as recrystallized, and grains of high orientation deviation are looked upon as deformed. Recrystallized grains are classified by their size and texture development is analyzed according to the annealing time and grain size variation. Texture of the recrystallized grains is relatively weak ?-fiber texture and significant fraction of {001}<110> texture at the early stage of recrystallization, but strong ?-fiber texture with {111}<112> peak is developed at the final stage of recrystallization. In every stage, small sized recrystallized grains have weak {001}<110> texture and it disappears in large size recrystallized grains.
