Abstract
Titanium alloy composites having substantially reduced reaction zones are provided which comprise a high strength/high stiffness filament such as silicon carbide, silicon carbide-coated boron, boron carbide-coated boron and silicon-coated silicon carbide, embedded in a fine-grained titanium alloy containing at least 40 percent beta phase, less than 7 percent Al and having a beta-transus temperature below 1750.degree. F. (955.degree. C.). Also provided is a method for fabricating titanium composites which comprises mechanically working a desired titanium alloy to obtain sheetstock in a desired thickness and having a relatively fine grain size, laying up a preform and consolidating the preform under increased temperature and pressure, 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 filament and the alloy matrix.
