“…Zhang et al [20] reported that the difference of hardness and yield strength between cladding and base layers would cause the change of interfacial morphology. Roostaei et al [21] adopted copper as intermediate layer to prepare aluminium/copper/aluminium trilaminar explosive welded composite plate, and the effect of annealing temperature on modelling of the composite plate was studied. However, the intermediate layer needed a certain thickness to ensure the stability in the collision process, resulting in the complexity of the welding process and the waste of materials.…”

In order to reduce critical impact velocity and enlarge weldability window of aluminium/steel explosive welding, a chemical copper plating layer as interlayer was proposed to carry out aluminium/steel explosive welding. The results showed that the interface of the 1060/Q235 composite plate had good bonding performance, and no obvious defects such as cracks and pores were found. Copper plating as intermediate layer could enlarge aluminium/steel weldability window. The thickness of solidified melt was much thicker than that of diffusion zone. The molten copper particles participated in the formation of re-entry jet, which rotated under the action of initial jet. The presence of the Cu layer reduces the occurrence of excessive melting during welding and improves the properties of the interface.

In this study, a constitutive model applied to predict the tensile properties and fracture behavior of well‐bonded multilayered metal composites is extended. The equivalent single‐layer model, as a convenient method, is introduced into finite‐element simulations by combining it with an improved Xue–Wierzbicki damage plasticity model that considers material anisotropy. The steel use stainless (SUS) 430/Al1050/SUS430 laminated sheet fabricated by cold rolling is selected as the research material. The quasistatic uniaxial tests and Nakazima tests are operated to verify the accuracy of the proposed method. The mean errors in tensile stress and fracture forming limit strains are 2% and 3%, respectively. A load‐sharing mixture rule is proposed to assess the effects of the volume fraction, strength coefficient, and hardening exponent of the constituent materials on the mechanical properties of the laminates. In the results, it is indicated that the laminate exhibits sufficient elongation and remains markedly enhanced in tensile strength, reaching 470 Mpa when the ductile Al layer is combined with the higher strength and hardenability steel layer. In this research, it is aimed to clarify the formability characteristics in laminated composites for optimal sheet configuration design and development.

The effects of heat treatment ((300–500 °C) × 30 min) on the interfacial structure, microstructure, and tensile properties of Al4343/Al3003/Cu composites prepared by different accumulative roll bonding (ARB) passes are studied by scanning electron microscopy, energy dispersion spectrometry, electron backscattered diffraction, and tensile tests at room temperature. The results show that the total thickness of the diffusion layer at the Al3003/Cu interface in the same ARB pass Al/Al/Cu composite increases with the increase in temperature. At the same temperature, the total thickness of the diffusion layer at the Al3003/Cu interface increases from ARB0 to ARB3 passes and decreases at ARB5 passes. In the same ARB pass Al/Al/Cu composites, the grains of Al4343 grow with the increase of temperature; the grain of Al3003 increases slightly from 300 to 400 °C, and grows along the interface direction after 500 °C. After 400 and 500 °C, the final average grain size of Cu decreases from ARB0 to ARB3 passes and increases slightly at ARB5 passes. The tensile properties of the composites are affected by recovery and recrystallization at lower temperatures and ARB passes, and by the total thickness and volume fraction of the diffusion layer at higher temperatures and ARB passes.
