Summary: In this study, the microstructure evolution and thermodynamic behaviors of platinum/titanium (Pt/Ti) bimetal composite were systematically investigated during the explosive welding (EW) process. The results revealed the formation of a straight metallurgical reaction layer at the Pt/Ti interface, which was attributed to localized melting and intense mechanical mixing. Furthermore, changes in grain structure near the interface and extreme thermodynamic states during the process were quantitatively analyzed using smoothed particles hydrodynamics (SPH) simulation.

Summary: This study demonstrates the advantages of interlayer explosive welding over direct welding by using both experimental and simulated results. The use of an interlayer was found to reduce excessive melting and large plastic deformation, enlarge the weldability window, and decrease the vortex region between interfaces. The simulated results from smoothed particle hydrodynamics (SPH) showed excellent correlation with the experimental results.

Summary: A comprehensive study was conducted to investigate the microstructure evolution, extreme thermomechanical behavior, and consequences of explosive welded CLAM/316L interface using multiple characterizations and SPH numerical simulation. The study revealed a tight bond with a wavy structure and vortices formed at the interfaces of the two welding materials due to remarkable temperature rise and rapid cooling under high-speed collision conditions. The SPH simulation reproduced the heating and cooling process of the interface and revealed the high heterogeneity of thermodynamic behavior. The EBSD analyses showed complex evolution of crystal structure at the bonding interface with vortex, including ultra-fine grains, columnar grains, equiaxed grains, deformed grains, and serious lattice distortion. The formation mechanisms of diverse grains were correlated with temperature histories and grain characteristics, involving crystallization from liquid, recrystallization from solid, and plastic deformation. The recrystallization at the interface was closely related to material properties, and the variations in dislocation density, plastic strain values, and thermal softening could be explained by different degrees of dynamic recovery and recrystallization.

Summary: This study investigates the explosive welding of 2A14 aluminum alloy and niobium with and without a 1060 Al interlayer through experiments and numerical simulation. The results show that direct welding results in a continuous molten layer with micro-defects at the joint interface, while the presence of an interlayer leads to straight and curled joints without imperfections. The tensile-shear strength of the composite with an interlayer is increased by 38.2% compared to direct welding. The numerical simulation reveals that the interlayer reduces the impact velocity, increases collision area and duration, and minimizes kinetic energy loss at the joint interfaces, preventing the formation of intermetallic compounds.

Summary: In this study, the explosive welding technique was used to join lead (Pb) and 316L dissimilar metals, resulting in a slight waveform structure at the interface without obvious defects or cracks. Microstructure characteristics and phase constitution were investigated through electron backscattered diffraction test and numerical simulation. Severe plastic deformation led to the formation of fine grains zone, sub-grains, twin structures, recrystallized structures, substructures, and deformed structures at the joining interface. The numerical simulation results corroborated the experimental findings of a slight waveform structure at the Pb/316L explosive welded interface.
