“…For the clad plate, the shape of the Mg alloy layer changes slightly, and the shape of the Ti layer deforms radically, so there is obvious separation between the Ti and Mg alloy layers (Figure6g). Additionally, the fractured surface of the clad plate shows a mixed mode consisting of brittle and ductile modes, as reported by Rouzbeh, Z [8]. and Wang, D [23]…”

“…Explosive welding is noted for its capability of offering high strength bonding and cladding metals that are unweldable or are difficult to weld by other methods. It has been developed as a promising way to clad dissimilar materials [5][6][7][8][9][10][11][12][13]. Thus, some attempts have been made to clad other materials on Mg alloys by explosive welding.…”

“…No discontinuities or separations in the bonding region were found. Rouzbeh [8] clad the AZ31B magnesium alloys with the AA1050 aluminum through explosive welding and observed that the interface was wavy, and no intermetallic layers formed in the interface. It indicated that an appropriate bonding was formed between aluminum and magnesium in the interface.…”

In this paper, the microstructure and properties of a Ti/Mg alloy clad plate manufactured by explosive welding were studied. The bonding interface was inspected by ultrasonic examination (US). The microstructure and the composition of the clad were characterized by OM and SEM. Properties were inspected by tensile test, shearing test, microhardness test and electrochemical corrosion. The results showed that the bonding interface of the clad plate was made up of straight areas and wavy areas. In straight areas, element diffusion occurred across the bonding interface. Additionally, in wavy areas, a melting zone occurred in the Mg alloy layer near to the bonding interface. Lots of light particles embedded on the melting zone. Tensile test results were comparable with the Ti sheet and the ultimate tensile strength of the clad plate demonstrated an 18% increase. The shearing strength of the clad plate was about 68–87 MPa. The microhardness of the clad plate was higher than that of the original sheets from the interface to 300 μm away. At over 300 μm, the microhardness of the clad plate decreased and approached the original sheets. Compared with the straight area, the hardness of the Mg alloy layer in the wavy area close to the interface increased by 12%. Corrosion results showed that the corrosion potential (Ecorr) absolute value of the clad plate increased by 24%, and the corrosion current density (icorr) value was 4 orders of magnitude lower, compared with the Mg alloy sheet. It was clear that the corrosion resistance of the clad plate was higher than that of the Mg alloy sheet. Cladding Mg alloy and Ti by explosive welding would improve the industrial applications of magnesium materials.

“…A variety of technologies were developed to provide layered materials, especially in the form of sheets, e.g. accumulative roll bonding, electromagnetic pulse or explosive welding [4]. The latter offers a unique possibility of obtaining even multi-layered sheets in a single manufacturing operation, but due to its nature, it generates a series of heterogeneities along the interfaces that may affect further processing stages of these products.…”

A multi-scale numerical investigation of local heterogeneities in the strain and stress fields occurring during forming of explosively welded layered metallic sheets is the main goal of the research. Explosive welding is a complex process involving various phenomena occurring in materials during an impact at high velocities and pressures, especially at the interfaces of colliding metals. As a result, the interface of the layered metallic sheets is often highly heterogeneous at the microscale level, what directly affects the sheet behaviour under subsequent forming conditions. To investigate this issue, the mesh-free numerical model of the explosive welding process is used first to recreate the characteristic features of the interface morphology. Various detonation velocities are used to provide diversified morphological features at the interface. Obtained results are then used as input data to develop the concurrent multi-scale finite element model of material behaviour under deformation conditions. The multi-scale modelling concept with explicit representation of the interface region is used. The highly refined heterogeneous FE mesh was generated in the interface region to capture local heterogeneities occurring at the microscale. Particular attention is put on numerical investigation of an influence of interface morphology in the welding zone on the development of the stress localisation that may directly lead to fracture initiation during forming.
