Contents

High-temperature components in gas turbines for power plants and aircraft engines as well as in modern steam turbine systems are subject to high mechanical stresses at temperatures that can reach up to 90% of the melting point of the materials used. In-depth knowledge of the loadings that occur and the properties of typical high-temperature materials, i.e., nickel and cobalt-based alloys, high-temperature steels and ceramic thermal barrier coating systems, is therefore essential for the safe design of such components.

The lecture first gives an overview of the requirements for materials in modern high-temperature components and discusses the essential loading types (creep loading, high-temperature fatigue, high-temperature corrosion, thermomechanical fatigue). The most important high-temperature materials, i.e., heat resistant steels, Ni-base alloys, Co-base alloys and thermal barrier coating systems, are then presented, with a focus on a sound understanding of the relationships between material composition, microstructure and application relevant properties.

Competencies / intended learning achievements

The students are able:
  • on the level of subject matter expertise:
    • to describe the essential thermal and mechanical as well as corrosive loadings in high-temperature components of gas and steam turbines
    • to explain the transfer of such component loads to laboratory tests on material samples
    • to explain the essential microstructural deformation and damage mechanisms under high temperature loadings
  • on the level of methodological expertise:
    • to derive the essential measures to enable steels, nickel and cobalt-based alloys for high temperature application
    • to apply this knowledge of the correlation of alloy, microstructure and properties to the material selection for high-temperature components
