The major goal of this program was to fully evaluate the potential of TaC-reinforced eutectic Co alloys, particularly cobalt-base, for use in aircraft gas turbine applications. The subjects covered in this report include Critical properties, identification and evaluation prestrain, thermal cycling, thermal cycling under load, low cycle fatigue, microstructural stability, long-time rupture, off-axis properties, oxidation, and hot corrosion Composition alloying to improve stress rupture behavior and Processing Solidification. Also included as appendices to this report, is work sponsored by the General Electric Company in areas of interest to the current effort. The subjects covered in these appendices include Background studies in monocarbide-reinforced eutectic alloys, impact, thermal shock, thermal cycling model, and coatings. Modified author abstract
