In this study, rolling processes for manufacturing of aluminum/alumina composite were used for first time. Indeed, three major methods for producing the composites were used, which each of methods had unique properties. These methods are consist of: (a) cold roll bonding (CRB), (b) continual annealing and roll bonding (CAR) and (c) accumulative roll bonding (ARB). Also, two various techniques for adding the reinforcement to matrix in each of methods were used. These techniques are consist of: (a) using the alumina particles and (b) using the anodizing process. Therefore, it can be expressed that six methods for producing the aluminum/alumina composites were used. Bond strength between strips and effective parameters on the bond strength were evaluated by peeling test. Microstructural observation during the various methods was investigated by optical microscopy (OM) and scanning electron microscopy (SEM). In order to investigation of mechanical properties of the produced composites, tensile and hardness tests were used. Evaluating the fractured surfaces of samples were carried out by scanning electron microscopy. The results revealed that when the cycles’ number of process was increased, porosities were decreased and the distribution of alumina particles in the aluminum matrix was improved. Also, tensile strength of the produced composite by the accumulative roll bonding method, improves by 4 times compared to that of the annealed aluminum used as the original raw material. The tensile strength of the composites were increased by increasing the number of cycles while the changes in elongation values were various. Furthermore, the results demonstrated that mechanical properties variations are in agreement with their microstructural observations. Finally, the observations revealed that the failure mode in ARB-processed composites is the shear ductile rupture type.
