An introduction to Advanced Research Projects Agency – Energy (ARPA-E)’s Ultrahigh Temperature Impervious Materials Advancing Turbine Efficiency (ULTIMATE) program as well as the program findings to date will be presented and discussed. The ULTIMATE program aims to develop ultrahigh temperature materials for gas turbines used in power generation and aviation industries, enabling them to operate continuously at 1300°C (2372°F) in a stand-alone material test environment, or with coatings, enabling gas turbine inlet temperatures of 1800°C (3272°F) or higher. The successful materials must be able to withstand not only the highest temperature in a turbine but also the extreme stresses imposed on turbine blades. Manufacturing processes for turbine components using these novel alloys are concurrently developed, enabling complex geometries that can be seamlessly integrated in the system design. Progress in environmental barrier coatings and thermal barrier coatings will also be presented.
