“…e content of the TiFe phase is less than that of the CuTi phase, which is due to the fact that the diffusion rate of Ti in Cu is higher than that of Fe in Cu, thus declining the brittleness of joints [72]. Norouzi et al [73] also studied the effect of bonding time on the property of the transient liquid-phase bonded joints with copper as the interlayer. e time required for complete isothermal solidification can be calculated by [71,74]…”

“…where W max is the maximum liquid width proportional to the initial interlayer thickness, K is a constant, and D is the solute diffusivity in the base metal. As the bonding time increases to 60 min, the amount of the intermetallic compound was decreased and only single-phase solid solution β-Ti existed at the interface, which gives rise to a maximum shear strength of 374 MPa [73]. Zakipour et al [75,76] investigated the influence of Cu interlayer's thickness on diffusion bonding behavior of stainless steel 316/Ti-6Al-4V system.…”

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.

“…The formation of TiCu and Ti 2 Cu instead of α+β-Ti and Ti 2 Cu in the bonding zone can be attributed to the insufficient holding time for the isothermal solidification. Norouzi et al [17] demonstrated that the eutectic and intermetallics compounds could be obtained in TLP bonding of TC4/steel with Cu foil if the holding time was insufficient for the completion of isothermal solidification.…”

Transient liquid phase bonding of graphite to Ti6Al4V alloy has been conducted with Cu foil, Ti/Cu and Cu/Ti/Cu foils, respectively. A diffusion zone containing Ti-based solid solution and Ti 2 Cu develops between the bonding zone and Ti6Al4V substrate for all the joints. The bonding zones of joints with Cu foil and Cu/Ti/Cu foils are both composed of TiCu and Ti 2 Cu. However, the bonding zone of joint with Ti/Cu foils consists of zones I, II and III. Both zones I and III are mainly comprised of TiCu and Ti 2 Cu, while zone II is a Ti residual zone. The joints with Cu/Ti/Cu foils exhibit the highest shear strength of 17.5 ± 1.7 MPa due to the most favourable interfacial bonding.

“…The diffusion bonding of Ti–6Al–4V to 304 stainless steel through 25 μm thick copper interlayer at 950 °C resulted in shear strength growing with the bonding time and reaching the maximum of 374 MPa at 60 min . Reaction interfaces contained ( β ‐Ti), Ti 2 Cu, Ti 2 Cu 3 , TiCu 2, TiCu 4 , CuTi, and FeTi phases for the bonding time of 45 min, however at 60 min, the interface contained mainly a ( β ‐Ti) solid solution, which was attributed to isothermal solidification.…”

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.
