Fe-Al-based ferritic superalloy nanocomposites containing sub-micron cuboids of intermetallic phases coherently embedded into a disordered Fe-Al solid solution are intensively studied as candidate materials for high-temperature applications. We focused on Fe-Al-based superalloys containing Ti [1,2] and Co  as ternary elements as well as Fe-Al binary nanocomposites . The transmission electron microscopy (TEM) revealed a superalloy nano-structure in these materials and the energy-dispersive X-ray (EDX) technique detected the composition of individual phases. Subsequently, quantum-mechanical calculations were used to determine thermodynamic, elastic and magnetic properties of constituting phases as well as selected nanocomposites . In particular, the theoretically predicted significant differences in the elastic response of different phases were confirmed also experimentally by room-temperature quasistatic nano-/micro-indentation and nano-scale dynamic mechanical analysis (nanoDMA). Regarding high-temperature macro-scale measurements, small-punch testing was performed and showed improved creep properties of the studied materials when compared with binary Fe-Al.
