Abstract: Cu-Fe particle-reinforced composites were prepared using the Accumulative Roll Bonding (ARB) technology. The hardness, electrical conductivity and friction wear properties of the composites under different cycling conditions were measured, with particular emphasis on the effect of rolling cycles number of the particle dispersion, interfacial bonding and wear mechanism of the composites. The results show that with increasing rolling cycles number, the interfacial bonding in the composites is gradually improved and the dispersion effect of the particle reinforcement is significantly enhanced. The material’s interface shows a fully welded state after 8 cycles. The Fe particles are diffusely distributed in the inter-plate, and the hardness of the material reaches the maximum value of 138.49 HV. However, compared with the low-cycle condition, both the electrical conductivity and the friction coefficient decrease, reaching 81.6% IACS and 0.337, respectively. The dominant wear mechanism of the composites gradually changes from fatigue and abrasive wear to adhesive wear as the number of cycles increases. When the number of rolling cycles increases to 6 and then continues to increase, the dominant wear mechanism shifts back to fatigue and abrasive wear.
