N2 - 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 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 energydispersive 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. In particular, the predicted significant differences in the elastic response of different phases were confirmed also experimentally by room-temperature quasistatic nano-/microindentation 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.
