“…In particular, the introduction of copper into aluminium/steel composite plate may lead to the formation of brittle Al–Cu intermetallic compounds. Fu et al [36] detected that Al 2 Cu occurred at the interface of copper/aluminium explosive welded composite plate. Al 2 Cu, Al–Cu, and Al 4 Cu 9 were found by Li et al after further cold rolling annealing of aluminium/copper composite plate [37].…”

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.
