Resumo(s)
The production of aluminum-carbon steel and aluminum-stainless steel clads is challenging,
and explosive welding is one of the most suitable processes to achieve them. The present work
aims to investigate the coupled e_ect of two strategies for optimizing the production of these
clads by explosive welding: the use of a low-density interlayer and the use of a low-density and
low-detonation velocity explosive mixture. A broad range of techniques was used to characterize the microstructural and the mechanical properties of the welds, specifically, optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, electron backscatter di_raction, microhardness and tensile-shear testing with digital image correlation analysis. Although aluminum-carbon steel and aluminum-stainless steel have di_erent weldabilities, clads with sound microstructure and good mechanical behavior were achieved for both combinations. These results were associated with the low values of collision point and impact velocities provided by the tested explosive mixture, which made the weldability di_erence between these combinations less significant. The successful testing of this explosive mixture indicates that it is suitable to be used for welding very thin flyers and/or dissimilar materials that easily form intermetallic phases.
