Brazing copper to alumina using reactive CuAgTi alloys

Wetting by Liquid Metals—Application in Materials Processing: The Contribution of the Grenoble Group

“…Even higher contact angles can be observed with further reduction in Ti concentration or, more generally, of titanium activity in the alloy, which is in reality the relevant thermodynamic quantity involved in the interfacial reactivity. Information obtained by the above sessile drop experiments provided useful information concerning brazing of alumina by CuAgTi alloys [41]. [40].…”

Cu+TiB2 composite filler for brazing Al2O3 and Ti–6Al–4V alloy

“…During brazing process, TiB in situ synthesize by the reaction of brazing filler leads to form increasingly Ti-rich intermetallics due to the increasing of Ti atoms dissolution. From the location and shape of Ti 2 (Cu,Al) and Ti 3 Al it may be concluded that they precipitate at the cooling [12]. Furthermore, the intermetallics formed during brazing temperature are also observed, mainly in the large block forms near Al 2 O 3 and Ti-6Al-4V alloy side.…”

Brazing of ZrB2–SiC–C ceramic and GH99 superalloy to form reticular seam with low residual stress

“…The bulk of the joint is composed of the remaining Cu mesh and Ag-Cu eutectic structure. In the eutectic structure of mesh holes, excessive Cu with about 2 at% solution precipitates in the form of dendrites due to the mesh dissolution [35]. As magnified in Fig.…”
