In this study, copper was processed by equal channel angular pressing (ECAP) up to twenty passes at room temperature to obtain a mixture of submicron and nano-grained structure under different deformation routes. As the cross sections of the specimens were circular, the deformation routes were varied by rotating bars through 0°, 30°, 45°, 60° and 90° between each ECAP pass designated as routes A, B
30, B
45, B
60 and B
C, respectively. In order to study the orientation of the elongated crystallites, EBSD analysis was carried out and tensile tests were used to evaluate mechanical properties. The EBSD data were analysed for a statistical characterization of the deformed matrix. The effectiveness of different deformation routes with a 120° die in terms of grain refinement was in the order of B
