Abstract: Single phase aluminium laminates of AA6063, AA2014 and AA6063/AA2014 composites were produced by accumulative roll bonding processed up to 6 cycles. The microstructure and texture of the initial materials and the sheets after 6 cycles were studied using electron backscatter diffraction and X-ray diffraction, respectively. It is observed that 6 cycles lead to an ultrafine grained microstructure. In both the single phase laminates and the composite the texture consists of the typical components for rolling and shear deformation of face-centred cubic metals. For all texture components, the intensity in the composite is about the average of the intensities in the single phase laminates. Therefore, the deformation process in the individual layers of the composite is comparable with that in the single phase alloys.
