| Description | Our modern industrialized society increasingly requires new structural materials for high-temperature applications in automotive and energy-producing industrial sectors. Iron-aluminides are known to possess excellent oxidation and sulfidation resistance as well as sufficient strength at elevated temperatures. New Fe-Al-based materials will have to meet multiple casting, processing and operational criteria including high-temperature creep strength, oxidation resistance and room-temperature ductility. Such desirable combination of materials properties can be achieved in multi-phase multi-component superalloys with a specific type of microstructure (the matrix contains coherent particles of a secondary phase - a superalloy microstructure). In order to design new Fe-Al-based superalloys, we employ a state-ofthe-art theory-guided materials design concept to identify suitable combinations of solutes. |
