“…In addition, the tensile strength of the composite plate is higher than that of the 5052Al (300 MPa) and ZA31B (240 MPa), which is caused by the work hardening during the welding process. Due to the strength and toughness of the Mg and Al plate, they differ greatly, and the bonding quality is poor in some previous works [7,21,39]; a span can be observed during the stress drop stage in the stress-strain curves, and interfacial debonding can be found after the tensile test. However, this phenomenon has not been observed in this work.…”

“…Therefore, the layered composites of magnesium and aluminum alloys are promising structural materials, due to combining the advantages of the two metallic materials and giving the opportunity to provide the unique functional and operational properties of the layered materials [6]. However, obtaining a high quality Mg/Al joint is still a challenging task, due to potential technical problems such as poor solubility of Mg in Al and formation of intermetallic compounds [7,8].…”

“…Due to the high bonding ability, explosive welding has drawn increasing interest in the manufacturing of aluminum and magnesium. Zeng et al [7] investigated the effect of inert gas-shielding on the interface and mechanical properties of Mg/Al composite plate and found that explosive welding under inert gas atmosphere can effectively improve the weld quality. Zhang et al [3] fabricated a AA6061/AZ31B composite cladding plate and carried out systematic research on the microstructure evolution and mechanical properties of the bonding interface.…”

In this work, an improved explosive welding technique was investigated to fabricate a thin Mg/Al plate, where an additional thin aluminum sheet was used as a buffer layer between the explosive and the Al plate, and the Mg plate was rigidly constrained by a steel plate to avoid excessive deformation. Moreover, the welding parameters were optimized using theoretical analysis and numerical simulation, and the interfacial behavior was simulated using the SPH method. The bonding properties of the achieved joints were investigated using microstructure observation and mechanical tests. It was concluded that this technique is an effective method for producing a thin Mg/Al composite plate. In both morphology observation and mechanical tests, an excellent bonding quality was confirmed. In addition, smoothed particle hydrodynamics (SPH) simulation revealed an extreme condition of local high temperature and plastic strain in the welding process, and the characteristic parameters of waves obtained using simulation are well congruous with the experiment.

“…This, however, mainly refers to the static properties. Examples of such tests can be found in works [4,[27][28][29][30][31][32][33][34][35], among others, which refer to explosively welded steels and other alloys such as Cu/Zn, Al/ Mg, Al/Ti, Cu/steel, Nb/Cu, Ta/Cu, and 316 L/CuCrZr.…”

The study presents the results of tests of local static and cyclic properties of an explosively welded AA2519-AA1050-Ti6Al4V layered material. In order to perform the analysis, tests were carried out with the use of microspecimens collected from 10 layers of AA2519-AA1050-Ti6Al4V material. Additionally, the determined static properties were compared with the results of an analysis based on microhardness measurement. Based on the test results, slight differences in static properties were found for particular layers of the material as well as a distinct softening of the AA2519 layer in relation to the base values. It was also found that the application of microhardness measurement for analysis of static properties can lead to their overestimation. Cyclic properties were described by the Ramberg-Osgood model. As in the case of static properties, the cyclic properties of particular layers of AA2519-AA1050-Ti6Al4V material differ insignificantly. The tests of cyclic properties showed that application for their description the Ramberg-Osgood model, based on parameters determined for whole range of plastic strains, can lead to significant errors in the modeling of a layered material. The cyclic instability of Ti6Al4V and AA2519 alloys has a significant influence on the parameters to be determined for material models of the analyzed material.

“…Besides selection of individual materials, selection of suitable production technologies and their optimization has recently been a primary research trend. Among the widely used manufacturing technologies are processes based on welding, e.g., explosion welding [15,16,17], or diffusion welding [18]. However, such processes have certain disadvantages, notably the development of a heat-affected zone, featuring significantly different properties and a different structure, which can negatively influence the performance of the final composite.…”

Analysis of Deformation Behaviour and Residual Stress in Rotary Swaged Cu/Al Clad Composite Wires

Both copper and aluminum are widely applicable throughout a variety of industrial and commercial branches, however, joining them in a composite provides the possibility of combining all their advantageous properties in one material. This study investigates uniquely sequenced copper–aluminum clad composite wires, fabricated via rotary swaging technology. The composites were processed at 20 °C and 250 °C to a diameter of 5 mm. Structural observations and the determination of residual stress within both elements of the swaged wires were performed via electron microscopy; the experimental results were correlated with numerical predictions. As shown in the results, both the applied swaging force and temperature affected the plastic flow, which had a direct influence on residual stress and texture development; the Alsheath elements exhibited ideal rolling textures, whereas the Cuwires elements featured ideal shear texture orientation. The grains within both the Alsheath elements of the 5 mm composite wire were refined down to sub-micron size. Structural restoration also had a positive influence on residual stress.
