“…The experimental loading ratio of 0.8, standoff distance of 7 mm, preset angle of 5°, and base plate with V grooves produced the maximum tensile (392 MPa) and shear (262 MPa) strengths, whereas the lowest loading ratio of 0.6, standoff distance of 5 mm, parallel arrangement without grooves produced the lowest strength (Tensile: 344 MPa, Shear: 220 MPa). According to earlier research [16], the lowest strength is attributable to the reduced kinetic energy and the absence of grooves. On the other hand, a base plate with a "V" groove delivers the highest strength (14% higher) for the midrange of process parameters.…”

In this study, an artificial neural network (ANN) model is created to predict aluminium-stainless steel explosive clads' tensile and shear strengths. The parameters for the explosive cladding process, such as the loading ratio (mass ratio of the explosive and the flyer, 0.6-1.0), standoff distance (5-9 mm), preset angle (0°-10°), and groove in the base plate (V/Dovetail), were altered. The ANN algorithm was trained in Python using the tensile and shear strengths gathered from 80% of the experiments (60), trials, and prior results. The constructed model was evaluated utilizing the remaining experimental results. The ANN model successfully predicts the tensile and shear strengths with an accuracy of less than 10% deviation from the experimental result.

“…For aluminium-magnesium and titanium-steel explosive cladding, flyer plate characteristics exert a more significant impact with regard to how the welding window emerges. The details of experimental conditions for the attempted combinations were reported elsewhere [14,15]. The experimental conditions (shown by bullets) prevailing inside the window would mean successful cladding with a wavy interface characteristic of a strong weld.…”

This study analytically estimated the welding domain for explosive cladding of aluminium-magnesium and titanium-steel combinations. Welding window, an analytical estimation, can ascertain whether the interface is wave-like or straight. The welding window’s lower, upper, left, and right boundaries were constructed using empirical relations suggested by peer researchers. The soundness of the dissimilar clad is primarily positioned near the lower boundary of the welding window. The ideal process parametric condition for an undulating interface is also laid out.

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.
