“…The second group of non-ferrous materials, which play a key role in electric engineering are copper and copper alloys. In literature the effectiveness of SPD methods has been revealed for a pure Al [7][8][9][10][11][12][13], Al-Mg alloys [13,14], pure Cu [11,[13][14][15][16][17][18][19] and Cu-Fe [20] alloys. Recent works have demonstrated [21,22] that one of the method which can be used for SPD processing is rolling with cyclic movements of rolls (RCMR).…”

“…Generally, this strengthening is introduced by work hardening and grain refinement. Previous papers proposed flow softening and microcracking as softening mechanisms [8][9][10]. Figure 5a and b illustrates the microstructures of pressed copper after one and three passes, respectively.…”

“…2 One of these advantages is a capability of producing large samples that are free from any residual porosity and readily amenable to mechanical testing and forming operations. 3 Among the various SPD techniques proposed for processing bulk materials, very few methods like accumulative roll bonding (ARB), 4,5 constrained groove pressing (CGP), 6,7 and repetitive corrugation and straightening (RCS) 8,9 are capable of processing sheet materials. The RCS process was invented recently, and it is a promising method for producing fine-grain-sheet material for structural applications.…”
