Texture Stability and Transition in an Accumulative Roll-Bonding-Processed Aluminum Single Crystal

Abstract

The crystal plasticity finite element (CPFE) model was used to simulate the textural evolution in a FCC aluminum single crystal of the {1 1 2}〈1 1 1〉 (Cu) orientation processed by accumulative roll-bonding. The simulation was conducted up to nine cycles, and the predictions have been validated by the corresponding experimental observations. The dynamic balance between the destroyed and formed texture components (0 0 1)[1 1 0] and $\left( { 4\; 4\; 1 1} \right)[ 1 1\; 1 1\;\bar{8} ]$, as representatives of shear-type texture and rolling-type texture, respectively, made their area fractions stable. Different deformation behaviors in the destroyed, formed, and preserved texture components (0 0 1)[1 1 0] and $\left( {4\;4\;11} \right)[11\;11\;\bar{8}]$ were found and investigated.
