Manufacturing of aluminium/copper/nickel(powder) metal intermetallic composite by accumulative roll bonding and subsequent heat treatment

Abstract

This study investigates the annealing effect on the tensile properties of aluminium (Al)/copper (Cu)/nickel (Ni)(powder) composite fabricated utilising the accumulative roll bonding (ARB) technique up to 11 passes. The results showed that the composite transformed into a layer/powder-reinforced fabric by increasing the applied strain. After the 11th pass, the Al and Cu layers and Ni powder were uniformly distributed in the composite. The tensile strength decreased for the second pass and increased as the ARB process proceeded. Upon annealing temperature and time increase, the tensile strength of the 3rd pass increased and for the 11th pass decreased. Also, as the annealing temperature and duration extended, the elongation for the 3rd and 11th passes fluctuated and remained almost unchanged.
