In this report, reverse accumulative roll-bonding (ARB) was conducted for the first
time. It was found that the microstructure after reverse ARB was relatively coarser than that after
unidirectional ARB, and texture intensity was slightly weaker. In addition to the experimental
study, the crystal plasticity finite element method was applied to the ARB-processed polycrystalline
aluminium. The simulation followed the real deformation of reverse ARB and unidirectional ARB,
and the predictions were validated by the experimental observations. Compared to the second
cycle of unidirectional ARB, the crystal orientations (after the first cycle) were relatively unstable
during the second cycle of reverse ARB, which is believed to be the reason for the relatively coarser
microstructure after reverse ARB.
