Model Calculation of Cross Rolling Textures

Abstract

Model calculations of texture formation during cross-rolling are carried out based on the full–constrained Taylor theory. Three variants of cross–rolling were considered i.e. two–stage, four–stage and multi–stage rolling. Three types of glide systems {110} 〈 111 〉 , {112} 〈 111 〉 , {123} 〈 111 〉 and all possible combinations of them were compared. The calculations were based on calculated orientation changes for grid points throughout the orientation space, taking the spread range according to the non–unique solution of the Taylor theory into account. The calculation were carried out in terms of the texture coefficients C ι μ ν . The best agreement between experimental and calculated orientation densities was obtained with {123} 〈 111 〉 glide systems.
