Abstract : Titanium-Aluminide metal matrix composites (MMCs) provide one of the enabling technologies needed in achieving the objectives of the Integrated High Performance Turbine Engine Technology (IHPTET) Initiative. These materials are targeted for applications that require high-temperature strength and stiffness, high creep and oxidation resistance, and acceptable ductility and fatigue resistance. The damage Tolerance Concepts for Titanium-Aluminide Composites Program addresses life management and reliability issues. Specific objectives of this program were to develop and establish design tools, behavior models, inspection methods, and Engine Structural Integrity Program (ENSIP) strategies required for alpha-two MMC fracture-critical components.
