Anodizing and accumulative roll bonding (ARB) processes were used as a new technique for manufacturing aluminum/alumina composites including various Al2O3 quantities. Textural evolution during ARB process of composites was evaluated using X-ray diffraction (XRD). The effective parameters in texture evolution were the number of cycles (3, 5, 7 and 8 cycles) and alumina quantity (0.48, 1.13, 2.40 and 3.55 vol.%). The texture evolution demonstrated that the Rotated Cube was a major texture component for all specimens except for the produced composite containing 0.48 vol.% alumina after eight cycles. For subsequent composites, the dominant components were Copper and Dillamore. Also, for almost all specimens (except for the composite with 0.48 vol.% alumina), the intensity of the texture components (except for Rotated Cube) was very weak. All these results are related to the presence of the second phase particles and also size and quantity of them. (C) 2011 Elsevier B.V. All rights reserved.
