“…The optimal type and size of the interlayer should make it easy to weld with the yer and target parts. The effects of gaseous media on a titanium/steel explosivewelded composite plate were reported by Zeng et al [15]. The results showed that a low-density helium medium smoothed the welding process and created a more stable periodic wave at the interface, and helium gas, an inert gas, effectively inhibited the formation of oxides at the interface and improved the mechanical properties and welding quality.…”

“…They share a similar bonding principle, namely the occurrence of an oblique collision at a certain speed and angle, after which a metallic jet is generated to remove the contaminants and oxides from the surfaces to be welded that are brought into direct contact, making the weld possible [10][11]. Many factors that have a considerable in uence on the quality of the joint formed by HSIW have been investigated, such as the interlayer [12][13][14], gaseous media [15], surface treatment [16][17], post-weld heat treatment [18][19], and geometric features of the surfaces to be welded [20][21][22], among others. Han et al [12] explored the effect of the thickness of the interlayer on an AA5083 aluminum/SS41 steel plate joint formed by EXW using AA1050 aluminum alloy as an interlayer plate.…”

A dissimilar metal tube joint fabricated by magnetic pulse welding (MPW) usually has uneven mechanical properties and an uneven morphology along the welding direction due to the small discontinuous matching range of the collision parameters. In this work, inclined, concave, and convex wall features were prefabricated on the target tube to improve the uniformity of the mechanical properties. The effects of the types of features and the prefabricated angle on the collision parameters, the axial distribution of the strength, and the interfacial morphology were investigated by simulations, shear tests, and microscopic observations, respectively. The results show that the collision parameters were increased with the increase of the prefabricated angle under the three types of features. Compared with the case without features, the increment of the collision parameters was found to be the greatest under the convex wall feature, and the smallest under the concave wall feature. With the increase of the prefabricated angle under the three types of features, the average shear strength tended to be reduced. When the prefabricated feature was the concave wall with a prefabricated angle of 5°, the quality of the joint was the best; it had an average shear strength of 46.46 MPa, an increase of 87%, and a low standard deviation of 4.96 MPa, a decrease of by 81%, as compared with that without geometric features. The transition layer was found to be the largest under the concave wall feature, and the maximum thickness decreased with the increase of the prefabricated angle.

“…Üretilen malzemeler sertlik, aşınma, korozyon direnci, iletkenlik, termal genleşme ve diğer mekanik ve fiziksel özellikleri bakımından saf malzemelerden daha üstündürler [2]. Bu tür malzemelerin üretiminde, iyi bilinen kompozit malzeme üretimi teknolojilerinden biri olan patlamalı kaynak endüstriyel üretimde yaygın olarak kullanılmaktadır [4][5][6]. Patlamalı kaynak, belirli miktarda patlayıcının patlatılması sonucu oluşan, deformasyon ısısı ve yüksek hızda çarpışmanın meydana getirdiği yüksek basıncı kullanarak kısa bir süre içinde metal ve biyolojik malzemelerin birleştirilmesini sağlayan bir işleme teknolojisidir [2,3].…”

Bu çalışmada, bakır (Cu) ve titanyum (Ti) levhalar patlamalı kaynak yöntemiyle farklı patlayıcı oranları kullanılarak birleştirilmiş ve Cu-Ti bimetalik kompozit malzemeler üretilmiştir. Üretilen Cu-Ti bimetalik kompozit malzemelerin birleştirme arayüzeyi üzerinde patlayıcı oranının etkisi mikroyapı çalışmaları ve mekanik testler ile incelenmiştir. Birleştirme arayüzeyi karakterizasyonu için, optik mikroskop (OM), taramalı elektron mikroskobu (SEM), enerji dağılımlı spektrometre (EDS) ve X-ışını kırınımı (XRD) yöntemleri kullanılmıştır. Birleştirme arayüzeyi mekanik özelliklerini belirlemek için ise çekme-makaslama, çentik darbe, eğme, burulma testleri ve mikrosertlik çalışmaları yapılmıştır. Mikroyapı incelemeleri sonucunda, patlayıcı oranı arttıkça birleştirme arayüzeyindeki dalgalanma arttığı ve bu artışa bağlı olarak da dalga boy ve genliğinde artış tespit edilmiştir. Ayrıca, R=3 patlayıcı oranında Cu4Ti ve Cu4Ti3 R=3.5 patlayıcı oranında ise Cu3Ti2, Cu4Ti3, CuTi2 ve CuTi3 intermetalik fazlarının oluştuğu tespit edilmiştir. Mekanik testler sonucunda ise birleştirme arayüzeyinde gözle görülebilir bir kaynak hatası oluşmadığı belirlenmiştir.

“…Pra żmowski et al [10] reported the influence of the microstructure near the interface of the fatigue life of explosively welded (carbon steel)/Zr clads.Li et al [11] reported that discontinuous intermetallic including TiFe 2 , TiFe and Ti fragments coexisted in the melted zone, and the equiaxed nanograins can be seen in the recrystallization zone and mixed zone. Zeng et al [12] showed that the formation of oxides at the bonding interface was effectively inhibited under the helium gas during explosive welding and the mechanical properties and welding quality were improved. Wang et al [13] showed that liquefaction occurred at the explosive interface layer in the electron beam welding process, which consisted of Fess, Fe + TiFe 2 eutectic, TiFe + TiFe 2 peritectic and Ti + TiFe 2 eutectic from the Fe side to the Ti side.…”

During the explosive welding, the bonding interface of welded materials was fast heated due to high strain rate and drastic plastic deformation. The periodical wave interface, with an amplitude of ~300 μm and a period wavelength of ~800 μm, was identifiable as a uniform wave interface formed in the bonding interface. The details of the formation of melting zone and mixing zone of welding materials at the interface were observed. Combined with the Ti-Fe binary phase diagram and the principle of diffusion welding, the phase composition and evolution process of the melting and mixing zone of the bonding interface were investigated by transmission electron microscopy (TEM) and energy dispersive spectrometer (EDS). Significance of the intermetallic compound was found in the mixing zone and melting zone, which was mainly TiFe, TiFe2, TiO2, Fe2O3 and some other intermetallic oxides. Meanwhile, the phenomenon of the titanium agglomeration and oxygen precipitation was observed in the melting zone. The bonding interface could be determined as a mixing welding of mechanical mixing, melting, diffusion and solidification that occurred in the mixing zone, and melting welding and diffusion welding mainly occurred in the melting region.
