Trends in High Temperature Materials Technology for Advanced Aircraft Turbine Engines

Approaches to the development of improved high temperature engine materials are reviewed. Emphasis is placed on emerging materials technologies and their potential benefits to aircraft gas turbine engines. Advances in materials processing technology are considered also, with emphasis on areas of potential cost reduction.

This review also examines a changing approach to the selection of turbine engine materials technologies for future development. This changing approach places greater emphasis on the overall economic benefits to the aircraft system rather than improved engine performance.
