The aim of the research is to investigate mechanical properties and sensitization behavior of the as cast FeAl-Mn-xSi-Calloys. The alloys were prepared by an induction furnace under an argon atmosphere. The results showed that the mechanical properties such as the ultimate tensile test (UTS) and elongation of these alloys were in the range (617.78-695.56 MPa) and 20.8-30.65% respectively. The hardness of these alloys was in the range of VHN 220-230. The Charpy impacts of these alloys were in the range 20-30 J. The microstructures of Fe-Al-Mn-xSi-C alloys were ɣ phase containing α phase dispersion and were not modified after sensitization at 1000 oC for 60 minutes.
