Techniques of severe plastic deformation have been of continual interest in the production of novel metallic microstructures. Among these, accumulative roll bonding has been extensively used to produce multi-layered composites. In the present study, a new manufacturing process for Cu/MoSi2-1vol% and 1.5vol% MoSi2 composites was developed by using Copper and nano sized MoSi2 particles as starting materials. After five ARB passes, it was showed the MoSi2 particles properly distributed in the copper matrix. With increasing strain during ARB passes strength and elongation of these composites increased. Structure and mechanical properties of these composites were studied within different stages of ARB process. Also, Electrical resistivity of the samples was measured by four point probe method
