%X Mechanical properties and sensitization behavior of Fe-Al-Mn-xSi-C alloys
have been investigated by using tensile test, Vickers hardness test, impact test,
scanning electron microscope and XRD. The aim of the research is to
investigate mechanical properties and sensitization behavior of the as cast Fe-
Al-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 1000oC for 60 minutes.
