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.
