ժҪ Texture is one of the important factors affecting sheet metal forming performance. The through-thickness texture gradient during the hot-rolling process of twinning induced plasticity (TWIP) steel sheet was investigated using electron backscatter diffraction and X-ray diffraction. With increasing reduction of the TWIP steel, the fraction of ��1 decreased, whereas the fractions of ��3, ��9, and ��27 increased. During 53% reduction, a similar trend could be found from its surface to the center. The gradients of intensities of the fibers decreased with increasing hot-rolling reduction. The intensities of face-centered cubic (fcc) shear textures E and Y were higher in the center than that at the surface for both reductions. During 20% reduction, the intensity of fcc plain strain texture S orientation increased from the center to the surface.
