Abstract
A method for controlling the interface in a titanium matrix composite between the titanium matrix material and a silicon carbide reinforcing filament or fiber which comprises treating such filament or fiber with a phosphorus-containing compound, and thereafter incorporating the treated fiber into a titanium matrix composite. The quantity of phosphorus remaining on the fiber, following treatment, can be miniscule, so long as at least a trace amount of phosphorus remains on the fiber.
