Abstract

Abstract The effect of lubrication on the evolution of microstructure and texture during hot rolling was studied by means of texture analysis and finite element method (FEM) simulations. Hot rolling with lubrication gave rise to the formation of uniform rolling texture in the whole thickness layers, whereas hot rolling without lubrication led to the evolution of the pronounced through-thickness texture gradients. FEM calculations reveal that a larger friction between roll and sample causes a strain state severely deviated from a plane strain leading to the formation of shear textures in the thickness layers close to the surface.
