Formation mechanism of {111} recrystallization texture in ferritic steels

Recrystallized ND//[111] texture is obtained from cold rolled ND//[111] matrix even in single crystals where no grain boundary exists. These ND//[111] recrystallized grains are analyzed to emerge by [112] rotation from cold rolled ND//[111] matrix. This rotation is related to {110}[111] slip systems operated during cold rolling. Recrystallized orientations from cold rolled {111}[110] single crystal are 18 degrees rotated around these [112] axes and deviate from ND//[111] by 6 degrees. Since this deviation is not recognizable in polycrystalline material owing to its symmetry, ND//[111] recrystallized texture in cold rolled commercial ferritic steels such as IF steels or electrical steels, may also be explained by the same [112] rotation, not by conventional ND//[111] rotation.
