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∑27increased.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.
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 diffraction. the TWIP steel, the fraction of Σ1 decreased, whereas the fractions of Σ3, Σ9, and Σ27 increase created 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. Intensities of face-centered cubic (fcc) shear textures E and Y were higher in the center than that at at the surface for both reductions. orientation increased from the center to the surface.
