Mechanism of formation of sharp cube texture was investigated by transmission X-ray diffraction at the same point of specimens after various thermal and mechanical treatments. In cube oriented grains formed by partial annealing after heavy cold rolling, lattice rotation occurs mainly around transverse direction during light rolling. Upon slow heating from room temperature, polygonization was observed in deformed cube grains. Polygonization was attributed to recovery in TD rotated cube regions. Cube grains grow by bulging out of those boundaries to unrecrystallized region. After formation of cube texture with orientational spread of around TD, grain growth begin on final annealing at high temperature among TD-rotated cube grains, resulting of formation of sharp cube texture.
