Paper Title:
Features on Grain-Structure Evolution during Asymmetric Rolling of Aluminium Alloys
  Abstract

The possibility of refining the grain structure of commercial Al-Mg-Si and Al-Mg-Mn alloys was evaluated using the asymmetric rolling technique in the severe plastic deformation regime. The study demonstrated that asymmetric rolling can readily promote the achievement of an ultrafine grained structure in the alloys investigated. Comparative analyses showed that by increasing the asymmetry ratio and by alternating the shear direction during rolling, higher hardness values and reduced crystallite size could be obtained in the alloys.
