Abstract
A method for fabricating an improved titanium alloy composite consisting of at least one high strength/high stiffness filament or fiber embedded in a titanium-aluminum base alloy matrix which comprises the steps of providing a rapidly-solidified foil made of the titanium-aluminum base alloy, fabricating a preform consisting of alternating layers of the rapidly-solidified foil and the filamentary material, and applying heat and pressure to consolidate the preform, wherein consolidation is carried out at a temperature below the beta-transus temperature of the alloy.
