New Methodology to Determine Stable Texture Components Under Cold Rolling in FCC Metals

Abstract

In this work evolution of texture components during deformation of AA5754 aluminum alloy sheet under cold rolling is studied by analyzing the evolution of element-rotation-distribution calculated using a rate -dependent crystal plasticity finite element model (CPFEM). The proposed criteria can successfully predict the stability of a given textural component for cold rolling deformation in FCC materials with high stacking fault energy that deform predominantly by slip. Comparison of simulation results with experimental data shows that this approach successfully captures the stable textures reported for cold rolled AA5754 sheets. With the initial texture and the strain path, it is believed that, the method described in this work can be used to predict the final stable textures without any need for expensive crystal plasticity based numerical simulations and this could be of immense help for simulating large strain deformation of macroscale sheet samples exhibiting texture evolution.
