Abstract : In accordance with the present invention there is provided an improved titanium composite consisting of at least one filamentary material selected from the group consisting of silicon carbide, silicon carbide-coated boron, boron carbide-coated boron and silicon-coated silicon carbide, embedded in an alpha-beta titanium alloy matrix. The method of this invention comprises the steps of providing a rapidly-solidified foil made of an alpha-beta titanium alloy, fabricating a preform consisting of alternating layers of the rapidly-solidified foil and at least one of the aforementioned filamentary materials, 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, thereby reducing the amount of reaction zone between the fiber and the alloy matrix.
