High temperature titanium braze foil |
摘要 |
The diffusion brazing of members comprised of materials which are characterized by embrittlement as a result of exposure to excessive temperatures is accomplished with the aid of preforms consisting of a titanium-zirconium alloy foil coated with a plurality of eutectic depressant alloying agents. The depressant agents, in a preferred embodiment, are applied as layers and consist of beryllium and nickel. The preforms are sandwiched between surfaces to be joined and the resulting assemblies are heated in a non-reactive environment with light pressure loading whereby a liquid phase will result and diffusion of metal from the preform into the base metals will occur.
