Currently, gamma alloys in specific alloy-microstructure forms are in service or about to be implemented in select aero-engines as LPT blades and in select automotive engines as turbocharger rotors and exhaust valves. Their service temperatures are limited to 750°C for LPT blades and around 900°C for turbocharger rotors. Greater service temperatures has been desired by the users and manufacturers for many years, and in spite of over one decade of efforts by both the materials RD community and industry, the limitations have remained virtually the same. The community’s inability in realizing the importance of systematic integration of accumulated data, knowledge and information (DKI), is the key reason for the lack of advances. This presentation assesses current alloys’ engineering microstructures, and identifies the application-specific alloy-processing-microstructure combinations that can be used at greater service temperatures up to 870°C for aero-engine rotational components and up to 1000°C gas temperatures for automotive engine components.
