“…Kumar et al [8] welded the Nb to 316L stainless steel using a new vacuum brazing technique and obtained a good welding interface with no brittle intermetallic layers. Wang et al [13,14] realised the joining of Nb and 316L stainless steel using the explosive welding technique. The results show that no brittle intermetallic layer was formed or any diffusion phenomenon observed.…”

“…The elemental analysis results indicated that a 5-µm diffusion layer was formed at the Nb-steel joining interface. In Wang et al's study [13], the electron backscatter diffraction (EBSD) analysis indicated that both Nb and SS grains were broken into smaller pieces after the explosive bonding, and the stainless steel part near the interface withstood the majority of deformation than the Nb part.…”

Niobium has a reputation for its superior superconducting, high strength and corrosion resistance at elevated temperatures. In this work, the explosive welding technique was successfully performed to join Nb/316L dissimilar metals. To reveal the phase constitution and texture distribution at the joining interface, the EBSD test was carried out. It was concluded that an irregular large wavy structure of fine crystal, sub-grains and twin structures was formed. In addition, the recrystallised structures, substructures, deformed structures and local internal stress at the joining interface were attributed to severe plastic deformation and rapid solidification of liquid metal. Furthermore, six different deformation textures and recrystallisation textures were confirmed at the joining interface due to severe plastic deformation and dynamic recrystallisation.

“…Solid-state welding like diffusion bonding and explosion welding have been developed to joint niobium with stainless steel. Some researchers have used explosive welding to manufacture composite material, such as niobium/stainless steel [12], or titanium/stainless steel/titanium [10,11], to fabricate transition joints. no vacuum leak has been detected on this type of transition joints even after a number of wide-range thermal cycles.…”

InvestIgatIon of the MIcrostructure and MechanIcal ProPertIes of BrazIng JoIntsBetween nIoBIuM and 316l staInless steel usIng sIlver-coPPer-PalladIuM fIller This paper introduces an approach for vacuum brazing of niobium-316L stainless steel transition joints for application in superconducting radiofrequency cavity helium jackets. The study takes advantage of good wettability of ag-Cu-Pd brazing alloy to suppress brittle Fe-nb intermetallic formation, hence improve the joints' mechanical performance. The wettability of ag-Cu-Pd filler metal on niobium, the interface microstructure and mechanical properties of the transition joints were investigated. Two kinds of ag-Cu-Pd filler metals had been studied and wet well on the niobium, and the wettability of ag-31.5Cu-10Pd filler metal on niobium was better than ag-28Cu-20Pd filler metal. Microstructure characterization demonstrated the absence of brittle intermetallic layers in all of the joint interfaces. Mechanical properties of samples prepared with ag-31.5Cu-10Pd filler metal were also better than their peers made with ag-28Cu-20Pd filler metal both room temperature (300 K) and liquid nitrogen temperature (77 K). The transition joints displayed shear strengths of 356-375 MPa at 300 K and 440-457 MPa at 77 K, respectively. after undergoing ten thermal cycles between the room temperature and the liquid nitrogen temperature, the transition joints' leak rates were all lower than 1.1×10 -11 mbar • L/s. Therefore, ag-Cu-Pd filler metal is applicable to high vacuum vessels used at cryogenic temperatures.
