An Experimental Study on Partial Texture Reversibility After Accumulative Roll Bonding of a Cube-Oriented Aluminum Single Crystal

In this study, the through-thickness texture of an accumulative roll-bonding (ARB)-processed aluminum single crystal was characterized using the Electron Backscatter Diffraction (EBSD) technique, and the texture reversal during ARB was investigated. Partitioned crystal rotation about the transverse direction (TD) and the activation of two sets of slip systems that resulted in TD-rotation and slip traces were evidenced. Reduced TD-rotation in certain layers of 2-ARB and 3-ARB corresponded to the destruction of previously formed slip traces, which resulted from the activation of the other set of slip systems. The partial texture reversal in ARB was experimentally revealed for the first time, and the revealing of texture evolution mechanisms helps with texture tailoring for better formability of ARB-processed sheet metals.
