英文摘要	Al/Cu/Ti/Cu/Al laminated composites were fabricated successfully by rolling with various rolling reduction at room temperature. It was found that the size of interior layer and Ti layer decreased gradually with the increasing of rolling reduction. The hardness values of Al, Cu and Ti layers increased linearly as the rolling reduction increased. The tensile tests showed that the larger rolling reduction was beneficial for the tensile strength increase, but the elongation decreased. The ultimate tensile stress of composite with 85% rolling reduction was 233 MPa. In-situ tensile test indicated that the crack initiated and propagated at Al/Cu interface. Due to the weak interface bonding strength and different plastic deformation capacity, the Al/Cu interface delaminated and the composites finally fractured. © 2019 Elsevier B.V.
