Abstract
The disclosure relates to a method of joining titanium and titanium based alloys to columbium at low pressure and low temperature, wherein a titanium foil is electroplated with layers of copper and nickel with a columbium sheet then being placed in intimate contact with the exposed layer. The materials are then heated in a vacuum to a temperature above the Ti-Cu-Ni eutectic temperature and below the beta-transus of the titanium material to provide a joining of titanium to columbium without materially altering the mechanical properties of the materials involved.
