Abstract
A method of forming a superalloy part comprises: forming a preform from tape, said tape comprising a base metal layer and a braze alloy layer, said base metal layer comprising fibrillated polytetrafluoroethylene and an oxygen-sensitive superalloy base metal powder selected from the group consisting of titanium, aluminum, hafnium, and chromium, and said braze alloy layer comprising fibrilated polytetrafluoroethylene and braze alloy; heating the preform in an hydrogen or vacuum environment. Another method of forming a superalloy part comprises using a tape comprising fibrilated polytetrafluoroethylene, said oxygen-sensitive superalloy base metal powder, and powdered braze alloy.
