TL;DR: In this paper, a sound joint was produced at a joining temperature of 400°C, achieving reasonable shear strength and re-melting temperatures more than 550°C above the initial melting temperature of the filler metal.
Abstract: In this study, Al2O3–ceramics were joined via TLP bonding using interlayers of eutectic Au–12Ge (wt%) and Au–3Si (wt%) solder alloys, respectively, with a melting temperature of 361 and 363 °C and Ni wetting layers. The Ni layers were part of a metallic multilayer coating (Ti/W/Ni) applied on the ceramic surface to ensure wetting and adhesion during the joining process. For comparison, a soldering process was performed as well by changing the multilayer structure to Ti/W/Au. With respect to the different joining processes the influence of the variation in wetting layers on the interface reactions, mechanical properties and re-melting temperature was analyzed by scanning electron microscopy, shear testing, and differential scanning calorimetry. It is shown that sound joint can be produced at a joining temperature of 400 °C, achieving reasonable shear strength and re-melting temperatures more than 550 °C above the initial melting temperature of the filler metal.

TL;DR: In this paper, a review summarizes the dissimilar welding of titanium alloys to steels over a period of ten recent years, involving the welding processes which are used for the diameters of the joints and the discussion for the forming mechanism of the interface.
Abstract: This review summarizes the dissimilar welding of titanium alloys to steels over a period of ten recent years, involving the welding processes which are used for the dissimilar welding of titanium alloys to steels, the mechanical properties of the joints and the discussion for the forming mechanism of the interface. Reducing the formation of brittle intermetallic compound (IMC) is a key requirement in the dissimilar welding of titanium alloys to steels, because the strength of the welding joints depends on the presence of IMC.
