Effect of Deformation Mode on Texture of Ultrafine-Grained Low Carbon Steel Processed by Warm Caliber Rolling

Abstract:

The evolution of crystallographic texture with equivalent strain, eq, was studied in low carbon steel bars fabricated using multi-pass warm caliber rolling. Finite element analysis was carried out to evaluate eq accumulated and strain components introduced with each pass through the rolled bars. The texture at characteristic deformation sites on the cross section in the bars was analyzed using the electron back-scattered diffraction method. Although the texture in the area around the center was dominated by a strong RD//<101>, in the other two areas, a RD//<101> texture was not produced. It is clarified that this difference results from three deformation modes during rolling. Consequently, the areas around the corners, where eq of over 5.7 is introduced, are filled with ultrafine ferrite grains of below 680 nm, and the texture in the areas is random regardless of the increase of eq.
