On The Ideal Orientations of Rolling Textures for FCC Polycrystals

Abstract

The textures that develop during rolling are among the most important factors affecting the properties of rolled sheets, as well as their behaviour in subsequent forming processes. For FCC polycrystals, the main ideal orientations of rolling textures are cube, Goss, brass, copper, Taylor and S. The behaviour of these ideal orientations during rolling are investigated in this paper. Analytical and numerical results for the stress states, slip distributions, lattice rotation fields and orientation developments are obtained using a rate-sensitive crystal plasticity model. The rate-sensitive results are compared with those obtained from the classical rate-independent Bishop and Hill theory. Comparisons are also made with the experimental observations reported by Hirsch and Lucke.
