Asymmetric rolling, in which the ratio of the upper to lower roll diameter was 2, has been used to introduce an intense plastic shear strain for the purpose of grain refinement and developing shear deformation textures through the sheet thickness to give rise to higher plastic strain ratios and strengths of aluminum alloy sheets. AA1050 sheets were asymmetrically cold rolled without lubrication and the textures and microstructures of the sheets were investigated by X-ray diffraction and electron back-scatter diffraction (EBSD) analyses. When subjected to several passes of asymmetric rolling, the sheets exhibited the textures approaching the ideal shear textures, {001}<110>, {111}<110>, and {111}<112> through the thickness and comprised fine-grained microstructures with high boundary misorientations. Finer grain microstructures were obtained at rolling reductions per pass of 5 and 50% than at 10, 20, and 30%. The results were were correlated to the l/d parameter, where l and d are the projected contact length and the mean sheet thickness in the deformation zone.
