| Abstract | Mechanical behavior of AA1100 aluminum alloy processed by accumulative roll-bonding was modeled on the basis of a generalized three-dimensional dislocation-density-based two-phase composite model. The simulated yield stress and cell size were compared with the experimental data, obtained by accumulative roll-bonding after several passes. A good agreement between experimental and simulated results was obtained. The results showed that both yield stress and average cell size of the ultra fine grained materials, produced by accumulative roll-bonding, can be simulated using a dislocation-density-based two-phase model. Moreover, dynamic recovery in cell interior was governed by cross slip, while climb processes were responsible for that in cell walls. |
