In order to study the explosive welding experimental fabrication technology of multi-layer dissimilar metal plates and the quality of bonding interface, three-layer steel/aluminum/steel composite plates with different thickness distributions were fabricated using the method of explosive welding when their total thicknesses remained same (total 5 mm). Then the stereomicroscope was adopted to investigate the shape of bonding interface and the formed mechanism was also analyzed. In addition, the micro-hardness (Vickers hardness, Hv) distribution of the composite plate in the thickness direction was studied by a low load Vickers hardness tester. The results show that the method of explosive welding can be used to fabricate three-layer steel/aluminum/steel dissimilar metal plates successfully. Meanwhile, wave bonding interface was formed between steel fly plate and aluminum middle plate, straight bonding interface was formed between aluminum middle plate and steel base plate. The maximum Hv value of welded plate appears at the bonding interface with high bonding strength. The bonding strength of both two kinds of welded interface was considered sufficient, which offers experimental support for the explosive welding of multi-layer plates.

The Cu/Al composites conductive head is widely used in hydrometallurgy as the core component of cathode plate. Its conductive properties directly affect the power consumption, and the bonding strength and corrosion resistance determine the conductive head service life. The Cu/Al conductive head prepared by explosion welding, cold pressure welding, and solid-liquid casting methods were investigated in this paper. The interface microstructure and compositions were examined by scanning electron microscope and X-ray energy dispersive spectrometry. The bonding strength, interface conductivity, and the corrosion resistance of three types of joints were characterized. The Cu/Al bonding interface produced by explosive welding presented a wavy-like morphology with typical defects and many of brittle compounds. A micro-interlocking effect was caused by the sawtooth structures on the cold pressure welding interface, and there was no typical metallurgical reaction on the interface. The Cu/Al bonding interface prepared by solid-liquid casting consisted mainly of an Al-Cu eutectic microstructure (Al2Cu+Al) and partial white slag inclusion. The thickness of the interface transition layer was about 200–250 µm, with defects such as holes, cracks, and unwelded areas. The conductivity, interfacial bonding strength, and corrosion resistance of the conductive head prepared by explosive welding were superior to the other two.

In this study, explosive welding was used in the cladding of aluminum plates to ship steel plates at different explosive ratios. Ship steel-aluminum bimetal composite plates were manufactured and the influence of the explosive ratio on the cladded bonding interface was examined. Optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive spectrometry (EDS) studies were employed for the characterization of the bonding interface of the manufactured ship steel-aluminum bimetal composites. Tensile-shear, notch impact toughness, bending and twisting tests, and microhardness studies were implemented to determine the mechanical features of the bimetal composite materials. In addition, neutral salt spray (NSS) tests were performed in order to examine the corrosion behavior of the bimetal composites.

Interface Bonding Strength

In this paper, the interface microstructure, elements’ diffusion features at the interface, and bonding properties in nickel-based alloy/carbon steel clad composite prepared by vacuum hot-roll bonding were investigated, comprehensively. The influence of element distribution on the interface bonding strength was revealed as well. The results showed that there was a 13 μm thick diffusion layer at the interface of nickel-based alloy/carbon steel composite plate, which was beneficial to a strong bond between nickel-based alloy and carbon steel, as well as the stable transition of mechanical properties in the thickness direction. Kirkendall voids and fine-grained structure (the grain size is about 41.5 nm) were observable by peeling off the nickel-based alloy cladding, which greatly promoted element diffusion and enhanced the interfacial bonding strength of the nickel-based alloy/carbon steel composite plate. The diffusion coefficient of Ni at the interface was about 2 orders of magnitude larger than that of nanocrystalline Fe. The shear strength reached up to 453 MPa, which was much higher than the minimum of 140 MPa defined in ASTM A-264 specifications. Furthermore, in the shear test, the fracture occurred on the X52 carbon steel side at the contact rather than at the composite plate interface.

T2 red copper plate and DT4C electrical pure iron plate were cladded by explosive welding. Microcosmic analysis and bonding strength of the bonding interface were also studied. Results indicate that the welded zone appears periodical wavy metallurgical interface and obvious element diffusion occurs in the interfacial zone. In addition, no separation happens after the bonding strength test and tension-shear test and the broken zone takes place in the T2 red copper part of the samples, indicating that the bonding strength of the welded interface can get no less than the strength of T2 red copper.

The stereomicroscope, microscopic metallograph and scanning electron microscope (SEM) were adopted to investigate the fracture mechanism of two-layer steel/aluminum composite plates impacted by spherical fragment. The composite plates with the same total thickness (5mm) were fabricated by the method of explosive welding. In ballistic experiment, the spherical fragments were launched by a 14.5mm slip chamber gun to penetrate the composite plate. The effect of the combination state of the interface on the fracture mechanism was analyzed based on the experimental results. The results show that the fracture mechanism of the steel front plate is shearing and plugging and that of aluminum rear plate is ductile prolonging deformation when the tied interface failed by tension (or shearing and plugging when the interface combination remained connected).A narrow adiabatic shear band was formed in the local yield plate damaged by shearing and plugging during the penetration process.

Abstract In order to study the interface characteristics and microstructure formation of Ti-Al composite plate, explosive welding was carried out with TA2 titanium as the fly plate and 5083 aluminums as the base plate. Optical microscope and electron microscope were used to analyze the microstructure of intermetallic compounds. SPH method was used to simulate the welding process of composite plates. The formation conditions and initial defects of intermetallic compounds were analyzed. The results show that most of the melted metal in the wave-front stays in the wave-waist region, and there was a relative velocity difference between the vortex and the titanium tissue, which led to the existence of small pieces of fragmentation. The outer layer of the vortex had higher velocity than the inner layer. The formation of Ti3Al, its antioxidant capacity wound lead to the formation of cracks. The temperature of outer vortex was higher than that of inner vortex, and the vortex has a transition layer of 5 μm, which is thinner than the transition layer of 8 μm between cladding plate and substrate. The jet was mostly composed of aluminum metal, and the interface jet velocity reaches 3000 m·s-1 and the interface temperature reaches up to 2100 K. Compared with the molten metal in the wave-back vortex, the jet temperature at the interface was higher, resulting in a thicker transition layer at the bonding surface. The residual stress at the interface wound cause the density of the material to increase.

The shield thermal neutron performance of two high boron alloyed stainless steel composite plates(HBASSCP) was studied by the method of neutron beam transmission of neutron source reactor. The testing results indicate that the shield performance of the composite material is heavily affected by the size and distribution of the boride. Although the radiationresistance of high boron alloyed stainless steel increases with boron content, but blocky and sparse hypereutectic boride will appear in matrix when boron content is high (more than 3%), and these borides are difficult to be broken during hot deformation, so the thermal neutron is easy to penetrate directly through the space and can not be absorbed effectively. The difference between the shield performance obtained from experiments and the theoretical calculation is small for HBASSCP containing hypoeutectic boride in core material, but it is great for HBASSCP containing hypereutectic boride in core material.
