Iron aluminides are promising structural materials for temperatures up to 700 °C. Among them, single-phase, B 2-ordered iron aluminides containing 35 - 50 at.% Al are of particular interest due to their exceptional oxidation and sulfidation resistance. However, their use is limited by low ductility, primarily caused by environmental embrittlement, especially in alloys with >40 at.% Al, and vacancy strengthening. Despite extensive research, the understanding of the combined effects of point defec
