“…The TA1 side shows the highest titanium (Ti) content, despite the presence of trace amounts of Ti in both Al1060 and Al7075. These findings provide further evidence of element diffusion at the bonding interface, a common phenomenon in explosive bonding processes [33][34][35][36]. Additionally, line scans were performed on the TA1/Al1060 interface under three different charge thicknesses, referred to as L1-L3 (Figure 13).…”

The titanium/aluminum composite materials overcome the limitations of single metal materials and achieve lightweight, high-strength, and corrosion-resistant properties. However, there have been no reports on explosion-welded composites of titanium alloys and seven-series aluminum alloys. Therefore, TA1/Al1060/Al7075 explosion-welded plates with three different explosive thicknesses were successfully prepared using Al1060 as the transition layer. The SPH-FEM coupled algorithm was employed to analyze the detonation process in detail and predict the interface under different explosive thicknesses. The results showed that during the explosion welding process, the high temperature, pressure, and high-speed impact resulted in significant plastic deformation and jetting phenomena at the bonding interface, which were in good agreement with the experimental observations. With the increase in explosive thickness, the TA1/Al1060 bonding interface exhibited a flat shape, while the Al1060/Al7075 interface transitioned from a flat to a wavy morphology. Moreover, the crack, vortex, and TiAl3 were observed at the interface. Mechanical testing results revealed that the composite plate with a 35 mm explosive thickness exhibited the best tensile, shear, and bending performance, indicating the optimal process parameter. This study provides significant support and reference for the application of explosion welding technology in titanium alloys and seven-series aluminum alloy composite materials.

“…The chemical composition and properties of materials are respectively given in Table 1 and Table 2. An explosive detonation velocity between 2000 m/s-3000 m/s is frequently used to weld copper and steel, too high or too low detonation velocity will lead to poor welding quality [10]. Here we choose diatomaceous silica-sensitized emulsion explosives whose density and detonation velocity is about 0.7 g/cm 3 and 2327 m/s respectively.…”

In order to improve the energy utilization rate and the bond quality of explosive welding, the local water environment method is used in present study.In this paper, several groups of high-quality Cu/Steel explosive composite pipes are prepared under local water environment. Optical microscope and mechanical property tests are conducted to analyze samples microstructure and mechanical properties. The results show that the waveform dimension of Cu/Steel bonding interface has a positive correlation with explosive layer thickness, and the miniature wavy bonding interface with the highest bonding quality is obtained by using the local water environment method. Compared with the traditional charge method, the consumption of explosives for the local water environment charge method is decreased about 60 % in the same case of experimental conditions. The local water enviroment method solves the problem of ablation damage at the contact surface between metal and explosives, and effectively reduces the diameter expansion phenomenon and end damage caused by boundary effect in the welding process. Through mechanical property tests, it was found that the yield strengths and compressive strengths of Cu/Steel specimens which created by the local water environment method are positively correlated with the explosive thickness.

“…Thus, explosive welding is widely used in the preparation of laminated structures, such as Ti/Fe, Mg/Al, Cu/Al, Ti/Al, Ti/Cu, and Cu/Fe. [1][2][3][4][5][6][7][8][9][10][11][12] As titanium-steel composite plate has the corrosion resistance of titanium, the high strength of alloy steel, and a good comprehensive performance that can be directly welded with other offshore steel structures. It has become an indispensable structural material for the modern chemical industry, bridges, and ships.…”

Herein, the interface characterization and tensile properties of TA1/Q235 composite fabricated by explosive welding are investigated in the temperature range 650-950 °C. The explosive-welded TA1/Q235 composite presents the periodic wavy bonding interface with both the vortex and solid-solid bonding regions. Some defects, including cavities, cracks, and brittle intermetallic compounds, are located in the melted zone of the interface wave. The compound layer comprises FeTi and Fe 2 Ti, with a thickness of 25 μm. In terms of high-temperature tensile tests, the elongation of the TA1/Q235 composite exhibits a tendency of first increasing and then decreasing with increasing tensile temperature. And the elongation reaches the peak value of 95% at 800 °C. The tensile strength basically decreases with increasing temperature, except for a slight increase at 900 °C. The failure of the TA1/Q235 composite is affected by both the discontinuous compound and the continuous compound layers. With the increase in tensile temperature, a continuous compound layer with a certain thickness dominates the failure of the TA1/Q235 composite.
