“…Explosive welding of Ta and other metals have received much attention so far, referring to, e.g., Ta/Cu/steel [5,21], Cu/steel [22][23][24] and Cu/Ta [25][26][27]. The Cu-Ta system is characterized by nearly zero mutual solubility of the components in the solid-state [28,29] and high structural and mechanical stability at elevated temperatures.…”

A systematic study of explosively welded tantalum and 304 L stainless steel clad with M1E copper interlayer was carried out to characterize the microstructure and mechanical properties of interfacial layers. Microstructures were examined using transmission and scanning (SEM) electron microscopy, whereas mechanical properties were evaluated using microhardness measurements and a bending test. The macroscale analyses showed that both interfaces between joined sheets were deformed to a wave-shape with solidified melt zones located preferentially at the crest of the wave and in the wave vortexes. The microscopic analyses showed that the solidified melt zones are composed of nano-/micro-crystalline phases of different chemical composition, incorporating elements from the joined sheets. SEM/electron backscattered diffraction (EBSD) measurements revealed the microstructure of layers of parent sheets that undergo severe plastic deformation causing refinement of the initial grains. It has been established that severely deformed areas can undergo recovery and recrystallization already during clad processing. This leads to the formation of new stress-free grains. The microhardness of welded sheets increases significantly as the joining interface is approaching excluding the volumes directly adhering to large melted zones, where a noticeable drop of microhardness, due to recrystallization, is observed. On lateral bending the integrity of the all clad components is conserved.

“…Friction joining of titanium and 304 stainless steel through nickel/tantalum had UTS almost identical to that of a standalone tantalum insert (388 and 394 MPa, respectively) . However, the combination of a 100 μm thick tantalum with a 200 μm thick beryllium bronze allowed enhancing UTS of explosion joints between titanium and 9Cr18Ni10Ti stainless steel from 718 to 1000 MPa . A wavy bronze/steel interface revealed a featureless 8 μm thick melted layer and a 5 μm melted layer with Ta particles precipitated in Cu matrix formed at the copper/tantalum interface.…”

Welding of titanium alloys with steels presents a high risk of cold cracking because of the formation of extremely brittle intermetallic phases associated with residual stress. The use of solid state and diffusion-based methods as well as a high power beam welding allow so far to achieve good tensile properties through the control of a local phase content. This review summarizes existing approaches for the creation of defect-free joints between titanium alloys and steels: direct joining without a filler material, the use of insert having full metallurgical compatibility with titanium, the use of insert compatible with stainless steel, and multilayer engineering.

“…An explosion can weld almost all metals, but in some cases a third layer might be used in order to bond materials that differ greatly in terms of their mechanical properties. 13,14 The aim of this study was to present original results and the progress in explosively welded AZ31/AA1050/AA2519 laminates, which have potential applications in the military industry. Detailed studies were carried out in order to characterize and better understand the microstructures at the bonding zones.…”

Explosive welding is a solid-state process used for the metallurgical joining of two or more dissimilar metals. In this process, the energy of controlled detonation is utilized to accelerate one metal plate into another. As a result of the collision, an atomic bond is formed. This paper describes a study of a laminate based on the AZ31 magnesium alloy, the AA1050 aluminum alloy and the AA2519 aluminum alloy. The test material was obtained using the method of explosive welding in a direct configuration AZ31/AA2519, with the intermediate layer made of AA1050 alloy previously rolled on the AA2519. The microstructure of the bonds was evaluated using scanning electron (SEM) and transmission electron microscopes with the SAED technique, while the chemical composition was assessed using energy-dispersive spectroscopy (EDS). The mechanical properties were examined with mini-specimen tensile tests and microhardness measurements. Between the joined aluminum alloys, an oxide layer was observed. It was also reported that the obtained joint is free of brittle intermetallic phases.Eksplozijsko varjenje je proces spajanja v trdnem stanju, ki se uporablja za metalur{ko spajanje dveh ali ve~razli~nih kovin ali zlitin. V tem procesu se izkori{~a energija kontrolirane detonacije za pospe{eno spajanje ene kovinske plo{~e z drugo. Kot rezultat izvedene detonacije je nastanek atomske vezi med obema materialoma. Avtorji so raziskovali nastanek laminata med Mg zlitino AZ31 ter Al zlitinama AA1050 in AA2519. Testni material so izdelali z metodo eksplozijskega varjenja v direktni konfiguraciji AZ31/AA2519 z vmesno plastjo, narejeno iz zlitine AA1050, ki je bila predhodno navaljana na zlitino AA2519. Mikrostrukturo eksplozijskega spoja so okarakterizirali z vrsti~nim elektronskim mikroskopom (SEM) in presevnim elektronskim mikroskopom, opremljenim s tehniko SAED, medtem ko je bila mikrokemijska analiza izvr{ena z energijsko disperzijsko spektroskopijo (EDS). Za dolo~itev mehanskih lastnosti so izdelali miniaturne natezne preizku{ance. Dolo~ili so tudi mikrotrdoto izdelanih spojev. Na meji spoja Al zlitin so opazili oksidno plast. Poro~ajo tudi, da na izdelanem spoju ni opaziti krhkih intermetalnih faz. Klju~ne besede: eksplozijsko varjenje, mikrostruktura, AZ31, AA2519
