ABSTRACT:
The low pressure braze bonding of members comprised of, for example, titanium and zirconium alloys is accomplished with the use of foil-type braze alloy preforms. The braze alloy preforms comprise a titanium-zirconium foil which has been coated on at least one side with a layer of nickel which functions as a eutectic depressant alloying agent. Upon heating, at a temperature below the beta transus of titanium, a liquid phase will form and the nickel will partially alloy with and migrate into the foil and workpieces and solidification of the resulting joint may thereafter be obtained.
