“…For MPW of aluminum alloy tubes with steel [11,16,17] and with copper [18] target tubes with wall thicknesses from 0.8 to 1.0 mm, the flyer impact velocity was reported in the range of 140 to 363 m/s. Likewise, the flyer impact velocity was reported in the range of 240 to 458 m/s for MPW of sheets for similar materials such as aluminum alloys [19,20] and for dissimilar materials such as aluminum and steel [21,22], and aluminum and copper [23,24]. The thickness of the sheets was in the range of 1 to 2.5 mm.…”

Magnetic pulse welding involves the joining of two metallic parts in a solid state by the use of a short and intense electromagnetic impulses and the resulting impact between the parts. The coalesced interface undergoes visco-plastic deformation at a high strain rate and exhibits a wavy shape at a microscopic scale. A practical estimation of the electromagnetic pressure, impact velocity and welded joint length as a function of the process conditions and the electromagnetic coil geometry is required but currently not available. Three novel analytical relations for the estimation of the electromagnetic pressure, impact velocity, and welded joint length for magnetic pulse welding of tubes and sheets, are presented. These relations were developed systematically, following a dimensional analysis, and validated for a wide range of conditions from independent literature. The comparison of the analytically computed results and the corresponding values reported in the literature has illustrated that the proposed analytical relations can be used for the estimation of the electromagnetic pressure and impact velocity for the magnetic pulse welding of tubes and sheets with a good level of confidence. The analytically calculated results for the welded joint length show a little discrepancy with the corresponding experimentally measured values. Further investigations and more experimentally measured results are required to arrive at a more comprehensive analytical relation for the prediction of welded joint length.

Interfacial corrosion performance is crucial to the reliability of Mg/Al explosively welded composite plates. Nevertheless, more understanding is required concerning such interfacial corrosion. In this work, a combination of numerical simulation and experimental investigation was used to clarify the microstructure evolutions of AZ80‐Mg alloy/1060‐Al explosively welded composite plate. The formation of interfacial wave structure and the thermodynamic state were insighted through numerical simulation, which further enhanced the correlation between the interfacial microstructural heterogeneities and the interfacial corrosion characteristics. Galvanic corrosion was produced by the significant potential difference between the AZ80‐Mg and 1060‐Al, with multiple micro‐galvanic couples in the vortex zone. The corrosion occurred near the interface and gradually advanced away from the interface. After 1 h, the composite plates exhibited severe corrosion with deep pits on the Mg side, while the Al side was less affected. Within the vortex, however, the Mg‐rich region underwent little corrosion, whereas the Al‐rich region underwent significant corrosion, attributed to the increase in pH value caused by the Mg corrosion.
