Abstract

The effect of friction on evolution of the microstructure and texture during hot rolling in the ferrite region was studied with secondary electromicroscopy (SEM), X-ray diffractometer, and FEM simulation. The friction between a roll and a steel sheet surface leads to the formation of notable through-thickness texture gradients. The finite element method (FEM) simulation shows that the large friction coefficient between a roll and sample results in a pronounced variation of equation image (shear strain rate) and large ε13/ε11 value which accounts for strong {110}<001> texture components and weak γ-fiber components at rolled sheet surface; whereas the friction condition do not exert notable effect on texture formation at the sheet center.
