“…This process can be performed through two consecutive steps of folding and forging. It is obvious that surface preparation is of great importance to attain reasonable metallurgical bonding between the layers as in the case of ARB and APB processes, since surface alumina oxide can be reduced by scratch brushing [28,29]. After roughening the surface by brushing followed by degreasing within the acetone bath, the foils were carefully stacked and pressing was performed immediately to avoid from re-oxidation and further contamination.…”

“…In this method, it is possible to produce a variety of metal-based composites reinforced with metals and ceramic particles, compared to other severe plastic deformation. 13,19,20 Also, without the need for heavy equipment and molds, large-sized specimens can be produced, with excellent mechanical and microstructural properties. 21 Despite the high mechanical and microstructural properties of the APB, fewer researches have been done than other methods of severe plastic deformation.…”

“…22 The researchers also investigated the APB process on Al, AlZnO 2 , and Al/SiC in separate investigations, all of which results in improved mechanical properties, reduced grain size in the aluminum matrix, the formation of high angle boundaries, and improved particle distribution with increasing strain. 13,19,20 As noted, all previously limited researches have been on the use of different reinforcing particles for aluminum matrix and the study of mechanical and microstructural properties. Despite the cases mentioned above of fine-grained materials and composite produced by the process of SPD, one of the most challenging issues in the use of them, especially sheets, is their formability; therefore, appropriate tests such as the spring-back tests are needed to determine the angular deviation of the sample produced.…”

For the first time in this study, the accumulative press bonding method was used to fabricate layer composites, including ceramic powder and metallic layers, and the spring-back as a functional plasticity test experimentally investigated. Al/Cu and Al/Cu/Al2O3 composites were successfully manufactured in five accumulative press bonding cycles, and in addition to spring-back evaluation, mechanical properties and plastic instability were investigated. The results showed that by the end of the third cycle, both composites were fully layered structure. However, in the fifth cycle in the Al/Cu/Al2O3 composite, plastic instability intensified and necking and fracture at all Cu layers observed due to the presence of particles in the interface and further differences in mechanical properties. As the number of accumulative press bonding cycles increases, the number of Al/Cu interfaces, which are the places where the reinforcement particles are dispersed, increases, thereby significantly improving the particle distribution and mechanical properties. The mechanical properties were improved by increasing the applied strain to the two composites, mainly due to the mechanisms underlying the severe plastic deformation processes, including cold working and microstructure improvement. The mechanical properties of the composite containing reinforcing particles improved the tensile strength and microhardness of both layers in all accumulative press bonding cycles, although the amount of elongation decreased slightly. The maximum tensile strength values of the two composites were obtained at the end of the fifth cycle, which improved the tensile strength for Al/Cu and Al/Cu/Al2O3 by about 2.65 and 2.42 times higher than unprocessed Al matrix, respectively. Experimental results of the spring-back evaluation showed that the composite with reinforcement powder due to the higher Young’s modulus had lower spring-back value. The amount of spring-back in both composites decreased with almost the same rate as the applied strain increased.

“…The APB process was developed based on the principle of accumulative roll bonding (ARB) process, but can be readily installed in both a laboratory and industrial environment. The APB process can be applied to sheet materials and thick billets of relatively large-scale dimensions, while the ARB process can only be applied to sheet materials [7][8][9]. This phenomenon does not change the long cycles to produce high strength by UFG.…”

Composites a material was developed to replace metal and alloys, because of the properties such as light weight and unique mechanical properties. Processing of aluminum-based composites has been developing by new manufacturing technology, namely severe plastic deformation (SPD), to produce unique of mechanical properties. Some of the methods used are; equal channel angular pressing (ECAP), accumulative roll bonding (ARB) and multi-axial forging (MAF). The results of some of these methods were compared with the latest method of new SPD, namely: repetitive press roll forming (RPRF). Based on grain morphology and mechanical properties, the result of RPRF has superior to another method. The properties produced by SPD technology was varies, the highest of hardness produced by RPRF process was 88 HV10, ECAP produced 65 HV10, MAF was 46 HV10 and ARB reached 50 HV10. While the highest of tensile strength produced by MAF was 237 MPa while the RPRF process just only around 147 MPa, but the ultrafine grains just only produced by RPRF method which is 0.9 μm, compared to other methods: MAF 1.2 μm, ECAP 5.7 μm and ARB is not so far with MAF that is equal to 1.4 μm. The RPRF process can be recommended for the interest of the aluminum-based composite materials processing industry. Because currently some component product by industries have been substituted from metal alloy materials to metal-based composites.
