“…Recently, by virtue of relatively low cost, lightweight, high corrosion resistance, and appreciable mechanical properties, high-quality joints between titanium alloy and stainless steel have found applications for nuclear fuel field, petrochemical, cryogenic protector, and aerospace industries [1][2][3][4][5][6][7]. Titanium alloys possess low densities, high strengths, and strong heat resistance, enabling them for a wide range of applications in petrochemical, aviation, and space industries [5].…”

“…In order to solve these problems, many welding methods have been practiced to investigate the joining between titanium alloys and stainless steels, mainly including brazing welding [7,[16][17][18][19][20], laser welding [2,5,6,[21][22][23][24][25], electronbeam welding [26][27][28][29][30][31], diffusion bonding [32][33][34][35][36], explosive welding [37][38][39][40], and friction stir welding [41][42][43][44][45][46][47]. Cu-based and Ag-based fillers were usually used to braze titanium/steel joints, while scattered brittle intermetallics, such as (Fe,Cu)Ti, Cu 4 Ti 3 , and CuTi [20,48] and Cu 4 Ti and CuTi 2 [7], were induced to the interfaces which were detrimental to the mechanical properties of the joints, and maximum possible tensile strength of the joints was found to be no more than 200 MPa [16][17][18][19][20]…”

High-quality joints between titanium alloys and stainless steels have found applications for nuclear, petrochemical, cryogenic, and aerospace industries due to their relatively low cost, lightweight, high corrosion resistance, and appreciable mechanical properties.is article reviews diffusion bonding between titanium alloys and stainless steels with or without interlayers. For diffusion bonding of a titanium alloy and a stainless steel without an interlayer, the optimized temperature is in the range of 800-950°C for a period of 60-120 min. Sound joint can be obtained, but brittle FeTi and Fe-Cr-Ti phases are formed at the interface. e development process of a joint mainly includes three steps: matching surface closure, growth of brittle intermetallic compounds, and formation of the Kirkendall voids. Growth kinetics of interfacial phases needs further clarification in terms of growth velocity of the reacting layer, moving speed of the phase interface, and the order for a new phase appears. e influence of Cu, Ni (or nickel alloy), and Ag interlayers on the microstructures and mechanical properties of the joints is systematically summarized. e content of FeTi and Fe-Cr-Ti phases at the interface can be declined significantly by the addition of an interlayer. Application of multi-interlayer well prevents the formation of intermetallic phases by forming solid solution at the interface, and parameters can be predicted by using a parabolic diffusion law. e selection of multi-interlayer was done based on two principles: no formation of brittle intermetallic phases and transitional physical properties between titanium alloy and stainless steel.

In this study, two aspects concerning with the thermodynamics of CaO–SiO2–VOx system were investigated. One aspect is about the effects of oxygen partial pressure on the phase relationships in CaO–SiO2–VOx system at 1873 K, and the other is the measurement of the standard Gibbs energy of formation of the vanadium compounds. In the first aspect, the phase relationships in CaO–SiO2–VOx system at 1873 K under oxygen partial pressure of 1.7 × 10−9 atm were determined, and the isothermal section diagram was constructed. Furthermore, by comparing this diagram with that under 6.9 × 10−11 atm, the effects caused by oxygen partial pressure on this system were elucidated. With the increase in oxygen partial pressure, the compound CaV2O4 that exists stably under 6.9 × 10−11 atm is oxidized to V2O3 and CaVO3. The solubility limit of V2O3 in liquid phase also increases remarkably, which results in the enlargement of the single liquid area. In the second aspect, the standard Gibbs energy of formation of CaV2O4, CaVO3, V2O3, and Ca2Si1−δVδO4 (0 < δ < 0.1) at 1873 K were measured. The determined values for CaV2O4 and CaVO3 are −1 259 468.9 ± 5090.5 J/mol and −963 479.8 ± 3298.6 J/mol, respectively. Then, the limit of oxygen partial pressure for CaV2O4 existing stably at 1873 K is determined to be 4.4 × 10−10 atm.

“…However, the explosive bonding process is difficult to control and not environmentally friendly. Edge welding in vacuum followed by hot rolling is another possible process for producing Ti-clad steel plates, but welding Ti to steel can be difficult due to the formation of brittle intermetallic compound phases [4][5] and as a consequence the welded edges may not be strong enough to hold the two dissimilar metals together when the welded plates are fed into rolling machine, causing splitting during hot rolling. Thus, alternative processes that can avoid these difficulties need to be developed for producing Ti-clad steel plates.…”

Abstract. Ti was diffusion-bonded to a grade of carbon steel containing about 0.13 wt% C. The diffusion-bonded specimen was then hot-rolled to a final reduction in thickness of about 71 %. There were no delaminations during hot-rolling. The cross sectional microstructures of specimens before and after hot-rolling were characterised using scanning electron microscopy, energy dispersive spectroscopy and optical microscopy. It was proved that it is technically feasible to produce Ti-clad carbon steel plates using a process of diffusion bonding followed by hot-rolling. It was also demonstrated that normal heat treatment procedures involving quenching and tempering can be applied to Ti-clad carbon steels after hot-rolling. The bond strength of the claddings would be determined by the intermetallic compound phases formed at the interface between Ti and carbon steel, which could be optimised by adjusting the conditions of diffusion bonding and hot rolling processes.
