Fe3Al intermetallic compound has attractive properties as high temperature structural materials, such as high strength, good oxidation resistance, low-cost and so on. However, their commercial application has been limited because of their poor toughness and limited workability. The combination of grain ultra-refinement and phase control is one of the most promising methods to improve their mechanical properties. In this work, we will present the nanostructure and superior mechanical properties of bulk Fe-Al-C nanoalloys made by mechanically alloying (MA) with subsequent spark plasma sintering (SPS).
