Interfacial Effect on Bending Property of Al/Cu/Al Laminated Composite Produced by Asymmetrical Roll Bonding

Abstract:

This paper is aim to investigate the interfacial effect on the bending property of Al/Cu/Al laminated composite produced by the asymmetrical roll bonding and annealing. The interfacial microstructure was observed by scanning electron microscope, and the three-point bending tests were conducted at room temperature. It is found that the interfacial layer near the faster roll is about 1 μm thickness and continuous, and the bending strength is increased by 4.4% in comparison with the interface near the slower roll. The results demonstrate that the shear deformation during asymmetrical roll bonding causes a severe interfacial fracture and makes a good interfacial bonding. The increase of bending load is ascribed to the interfacial improvement.
