Abstract: In the current study the accumulative roll bonding (ARB) process was used for manufacturing Al/nanoAl2O3 composites. For this purpose Al 1050 powder was first milled with nano Al2O3 particles to produce nano composite powders. The powders were added between two Al strip and ARB process was applied to produce Al/nanoAl2O3 composite. The process was repeated up to nine passes. The resulting microstructures and the corresponding mechanical properties of composites after different passes of ARB process were studied by optical and electron microscopy, hardness and tensile tests. The produced MMC by nine ARB cycles showed a homogeneous distribution of nano particles in the aluminum matrix. Moreover, when the number of ARB cycles was increased, up to the cycle five, the tensile strength of composite strips was decreased and then by increasing the number of cycles, the tensile strength of composite strips was increased.
