• # Abstract

In the present research, laminated Al–Cu–Mg composite was processed by the accumulative roll bonding (ARB) method. Initially, aluminium, copper and magnesium strips were alternatively stacked together. Then these stacked strips were rolled at 150$^{\circ}$C up to five ARB cycles. The microstructure of composites was studied by optical microscopy. Micro-hardness and tensile tests were conducted to evaluate mechanical properties of the processed composites. After thefirst cycle of ARB, it was observed that copper and magnesium layers were necked and fractured. With increasing ARBup to four cycles, laminated Al–Mg–Cu composite with homogeneous distribution of fragmented reinforcement in matrixwas produced. It was observed that with increasing ARB up to four cycles the strength and micro-hardness of fabricatedcomposites increased and elongation decreased at the same time. These differences in mechanical behaviour have beenattributed to the microstructural aspects of the individual layers and the fragmentation processes.
