On the inhomogeneous rolling texture transition

Abstract

A simple model of rolling deformation, capable of predicting both plane strain and inhomogeneous rolling conditions is presented. This is used to show how both surface and subsurface inhomogeneous texture components arise. The effects of stacking fault energy on inhomogeneous rolling texture formation are postulated to arise from a twinning of the inhomogeneous rolling texture components, followed by co-rotation, shear banding and slip, to give rise to a texture very similar to the homogeneous brass texture. The feasibility of the theory is established using copper rolled at 77 °K.
