French Research and Development Activities on High-Performance Superalloys for Gas Turbine Components

Abstract:

For several decades, strong efforts have been made in France in research and development activities dedicated to nickel-based superalloys for high-pressure disks and blades. New superalloys were designed then developed within cooperative research programmes bringing together research institutes, alloy producers and engine manufacturers. Continuous research activities were carried out on these alloys in order to perform detailed analyses of the relationships between process parameters, chemistry, microstructural features, deformation mechanisms and mechanical behavior. Typical studies are illustrated by examples outlining some recent results.
