A Combined Experiment and Crystal Plasticity FEM Study of Microstructure and Texture in Aluminium Processed by Reverse and Unidirectional Accumulative Roll-Bonding

Journal Article


Abstract


  • 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.
