“…Besides, the poor wettability between Al alloy and Ti alloy is also a problem that cannot be ignored, which seriously affects the forming of Al/Ti welded joint [7,8]. It is worth noting that a series of approaches including laser beam welding [9,10], friction stir welding [11][12][13], diffusion welding [14,15], brazing [16,17], explosive welding [18,19] and ultrasonic spot welding [20][21][22] have been attempted to join Al/Ti dissimilar alloys, which are limited by specific operational environment and joint configuration.…”

TIG welding-brazing features of 5052 Al alloy and Ti6Al4V alloy in butt configuration with Zn foil additive were studied with varying welding heat input. The joint morphology, mechanical performance, microstructure and joining mechanism were investigated in terms of experiment observation and analysis. Results reveal that the TIG welding-brazing process was successfully developed to join 5052 Al alloy and Ti6Al4V alloy. With low heat input, a mass of residual Zn and a thin TiAl 3 IMCs layer occurred in the fusion area and brazing area respectively. And with optimal heat input, both the homogeneous diffusion of Zn atoms and the formation of clubbed interfacial reaction layer were beneficial to enhance joint performance. The optimized Al/Ti joint with the maximum joining strength of 192MPa was obtained under the current of 90A. Fracture occurred in the weld seam zone adjacent to the interface of Al/Ti and the fracture morphology was characterized by typical dimples and tearing ridges.

“…The character of the diffusion zone depends on the mutual solubility of the alloy chemical components. As a result of the diffusion changes within joint zone it is possible of brittle intermetallic compounds to be formed, new solid solutions or precipitates [29,30]. The important phenomenon, which can take place during heat treatment of the bimetal system is the Kirkendall effect, which results in the formation of the voids in the joint area as a consequence of the differences in diffusion rates of specific alloying elements of the welded materials [25,27,[31][32][33].…”

Inconel 625 and steel P355NH were bonded by explosive welding in this study. Explosively welded bimetal clad-plate was subjected to the two separated post-weld heat treatment processes: stress relief annealing (at 620 °C for 90 min) and normalizing (at 910 °C for 30 min). Effect of heat treatments on the microstructure of the joint has been evaluated using light and scanning electron microscopy, EDS analysis techniques, and microhardness tests, respectively. It has been stated that stress relief annealing leads to partial recrystallization of steel P355NH microstructure in the joint zone. At the same time, normalizing caused not only the recrystallization of both materials, but also the formation of a diffusion zone and precipitates in Inconel 625. The precipitates in Inconel 625 have been identified as two types of carbides: chromium-rich M23C6 and molybdenum-rich M6C. It has been reported that diffusion of alloying elements into steel P355NH takes place along grain boundaries with additional formation of voids. Scanning transmission electron microscope observation of the grain microstructure in the diffusion zone shows that this area consists of equiaxed grains (at the side of Inconel 625 alloy) and columnar grains (at the side of steel P355NH).

“…The explosive-welding method makes it possible to produce laminates made of different materials that are typically impossible to join using conventional methods of welding. [4][5][6][7][8] Joining by explosion belongs to the group of pressure welding and is used in the production of application components where high strength, wear resistance, corrosion resistance or strength of the applied surface layer of the material is required. 5,[9][10][11][12] This method significantly reduces the cost of the materials and makes it possible to connect materials types that would otherwise be difficult to join.…”

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
