“…So far, much work has been done to test the explosive welds in heat-treated conditions because it is indispensable in processing these materials. The literature mostly presents the information on the microstructure collected by light microscopy and scanning electron microscopy (SEM) (Gloc et al, 2016;Ning et al, 2017;Prazmowski et al, 2017;Chu et al, 2019). A typical Ti/steel interface has a wavy morphology with locally occurring remelting, which is the part of microstructure that is the most frequently presented in scientific reports.…”

This paper presents the comparison of the microstructure of the interface zone formed between titanium (Ti Gr. 1) and steel (P265GH+N) in various processing stages—directly after explosive welding versus the annealing state. Transmission electron microscopy technique served as an excellent tool for studies of the sharp interface in-between the waves. Directly after the welding process in this area, a thin layer of the metastable β-Ti (Fe) solid solution was observed. In the next step, two variants of annealing have been employed: ex situ and in situ in TEM, which revealed the complete information on the interface zone transformation. The results have shown that during the annealing at 600°C for 1.5 h, the diffusion of carbon towards titanium caused the formation of titanium carbides with a layered arrangement. Compared to our previous studies, the carbides found here have a hexagonal structure. Furthermore, changes in the dislocation structure were observed, indicating the occurrence of recovery processes. Possible reasons for differences observed in the microstructure of the interface formed due to ex situ and in situ annealing are also discussed. The microstructure observations are accompanied by the microhardness measurements, which showed that the annealing caused a significant reduction in the microhardness values.

“…This technology offers great opportunities, however, it is associated with several characteristic phenomena, the effects of which may turn out to be undesirable. Basic description of the idea behind explosion welding is that chemical explosion can be used to accelerate one of the components to very high velocity [6][7][8]. During collision at high velocity, the severe material deformation, high temperature gradients and phase changes occur and leave a trace in the material in form of shrinkage cracks [9,10], adiabatic shear bands [11,12] and residual stress [13][14][15] .…”

Methods of joining dissimilar materials gain interest and attention of highly demanding branches of modern engineering. Acquiring high-quality bond between steel and titanium or zirconium alloys is perceived as especially advantageous in terms of high strength and corrosion resistance. In the present paper results of fatigue tests performed on five different metal composites produced in the process of explosive welding has been gathered. All tested materials were manufactured by a collision of zirconium flyer plates with base plates made of steel or steel-titanium bimetal. Fatigue tests have been conducted under uniaxial force-controlled tension-compression conditions with a constant amplitude of load applied parallelly to bonding interface. The analysis includes the residual stresses measured by the hole-drilling strain gauge method in the flyer plates and the applied stresses calculated by three different models. A description of the initiation and propagation of cracks developing within the joint during cyclically changing loading is also included. Based on the collected data, application conclusions were formulated regarding the optimal use of the tested materials.

Products made of clad sheets are a cost-effective alternative to products made entirely of cladding material. The cladding process aims to enhance functional properties, such as corrosion resistance and tribological properties, or modify mechanical properties and conductivity. This publication analyzes the influence of the rolling method on the cold forming ability of explosive welded Ti/steel sheets. Special attention was paid to the quality of the connection between the sheets, as it significantly impacts clad sheet formability. The drawability of these clad sheets was assessed based on the mechanical and technological properties, as well as through microstructural analyses. Experimental analyses revealed that hot rolling of the clad leads to the disappearance of the wave character of the interface and formation in its area of the Frenkel plane and interface layer, which significantly affect the mechanical and technological properties of the analyzed clad. Better cold forming ability, especially in reverse bend test, were obtained for asymmetrically rolled clad, which exhibits greater uniformity of structure.
