“…[10][11][12][13][14][15] Recently, a novel process-roll cladding-was considered to improve the corrosion resistance and formability of Mg alloys. 16,17 Specifically, Al-cladding of Mg alloy sheet could combine the superior corrosion resistance and formability of Al with the high strength-to-weight ratio of Mg substrate. Previous studies showed that Al-cladding of Mg alloy sheet by hot and cold rolling process improved its surface corrosion resistance and room-temperature formability.…”

“…However, with the development of science and technology and the emergence of various new industries, it is increasingly difficult for a single material to satisfy the requirements of production. As a result, composite materials made of different metals or alloys with special structures and higher properties have attracted more and more attention [1][2][3].…”

Abstract-Aluminum laminated composite (ALC) is a new type of structural material with a broad application space and development prospects. Due to the laminated structure, the mechanical properties and failure patterns of ALCs differ significantly from those of uniform materials. The friction stir welding (FSW) of Al alloy can effectively avoid many defects caused by fusion welding, but the FSW of ALCs is in its infancy stage. Friction stir welding experiment of 7B52 ALC was carried out in this study. The Vickers hardness test, tensile test and impact test were performed on the specimens of the joint and base metal to analyze the effect of friction stir welding on microhardness, tensile properties and impact properties. The fracture surfaces were observed by SEM to investigate the fracture mechanism. A defect free weld was obtained. However, the laminated structure was destroyed, resulting in the decrease of microhardness and tensile strength. The microstructure of the weld was improved, significantly increasing the impact toughness.

“…There are many factors would affect the final bonding strength and the formation of interfacial-bonding area [3][4][5]. Besides bonding temperature [3] and annealing treatment [4], reduction ratio is one of the most important parameters. It is commonly reported that bonding strength of a laminated composite increases with the reduction ratio [1,[4][5], due to the increase contact mean pressure and the overlapping surface exposure at the interface.…”

Abstract.Reduction ratio is one of the most important parameters that affect final bonding strength of laminated composites fabricated by hot rolling. In general, the bonding strength increases with the reduction ratio. However, it was found that the reduction ratio had a reverse effect on the bonding strength of the 7075 Al/AZ31B Mg/7075 Al laminated composites prepared by hot rolling. Microstructure, elements distribution, and phase constitution in the bonded interface of the laminated composites at different reduction ratios were investigated, and the hot rolling process was simulated by finite element methods (FEM). The results show that a larger reduction ratio would lead to: a wider of diffusion layer with a relatively lower strength; a larger secondary tensile stress; and a larger relative slipping distance after the formation of the bonded interface. All of them induced the reverse effect.
