It is known since long that Fe–Al alloys based on Fe<SUB>3</SUB>Al (D0<SUB>3</SUB>) and FeAl (B2) have an excellent corrosion and wear resistance. Because of considerable lower density and appreciable costs, they could provide an alternative to stainless steels and Ni-base superalloys. However, inadequate strength at high temperatures still delays any wider application of these alloys. Through novel alloy concepts, e.g. precipitating fine-scaled borides or Laves phases along grain boundaries, coherent microstructures or increasing the D0<SUB>3</SUB>/B2 transition temperature, substantial progress in strengthening iron aluminide based alloys at high temperatures has been achieved. This progress as well as economic considerations led to a renewed interest in these materials by industries. Casting, rolling, forging and additive manufacturing of these advanced iron aluminides was successfully performed and the microstructure/property relations of the industrially processed alloys were established.
