In this study, the effects of strain routes in Accumulative Roll Bonding (ARB) on the mechanical properties and microstructure of sheet aluminum samples were examined. The routes were considered as direct rolling (route A) and cross-roll accumulative roll bonding by the rotation angle of 90 degrees in one direction continuously (route B C ), ± 90 °(route B A ), and 180 ° (route c). This study used commercial pure aluminum sheets with the thickness of 1 mm , and the dimensions of 5 15 cm for direct rolling in 180 degrees and 10× 10 cm for the rotation of 90 degrees. Studies addressing the mechanical properties through hardness machine and tensile route test have shown that due to the increase in dislocation density and finer grains, the hardness and tensile strength were increased by the number of cycles in the processes. However, the growing increase of hardness and strength in the rolling route by the rotation angle of 180 degrees was considered as the maximum value due to anisotropy and higher dislocation density. On the other hand, the minimum value was found to be in the direction of ± 90 ° due to the Baushinger effect, anisotropy and dislocation density. Hardness, after 8 cycles, compared to the annealed sample in routes A, C, B C and B A , was found to be 2.60, 2.63, 2.56 and 2.51 times, respectively. By applying the first-cycle processes, yield and tensile strength were increased intensively, but the rate of increase in strength was decreased in the subsequent cycles. Also, the strength, after 8 cycles, compared to the annealed sample in routes A, C, B C and B A , was observed to be 2.83, 2.90, 2.73 and 2.70 times, respectively. Elongation fell sharply during the first cycle, but it was increased in the subsequent cycles. Scanning electron microscope images were in different routes and analysis through image analysis software indicated that the equiaxial and ??shallower dimples were made by increasing the number of cycles at each route. This showed that the samples were greater in ductility and softne also, the mean diameter was the highest in route C and the lowest in route A. According to the results obtained by the conducted tests, route C was selected as the best in terms of mechanical properties.
