Single phase aluminium laminate sheets of AA6063, AA2014 and AA6063/AA2014 composites were produced by accumulative roll bonding (ARB). The microstructure and texture of the sheets up to 6 ARB cycles were studied using electron backscatter diffraction and X-ray diffraction, respectively. In all laminates the texture consists of the typical components for rolling and shear deformation of fcc metals. The intensity of the texture components in the composite is about the average of those in the single phase laminates. Similarly, the tensile strength and micro hardness of the composite is about the average of that of the single phase laminates while the ductility is about the same. Comparison of the micro hardness of the individual layers in the different laminates shows that in the composite strain partitioning takes place between the soft and hard layers. The strength will be discussed with regard to solid solution, precipitation, dislocation and grain size hardening.
