Description

Fe-Al-based superalloys represent a promising class of materials with large potential for high-temperature applications. Their mechanical properties can be modified and tuned by adding different intermetallic compounds. To achieve an understanding of the impact of such alloying additions we have performed a systematic theoretical study of intermetallics which form when adding Ti or Co, with a particular focus on Fe2TiAl and Fe2CoAl. As a complement to our theoretical research (see our results in Refs. [1-7]) we have performed an experimental investigation of Fe-Al-based materials (see Refs. [8-12]).
