Abstract In the course of studies on the iron-rich multicomponent system Fe-Mn-Cr-Mo-Nb-Al-Si-C, work was concentrated on pertinent quinary and six-component combinations namely Fe-Mn-Al-Si-C, Fe-Cr-Al-Si-C and Fe-Mn-Cr-Al-Si-C which had been elaborated at 65, 72, and 80wt% Fe. From these systems the following conclusions are obvious. Manganese acts as a strong stabilizer for the cementite carbide. Chromium and silicon, when present together prefer to occur as separate phases. However, a small portion is found as intermetallics such as CrSi2 or (Fe, Mn)5Si3. Chromium seems to stabilize the iron aluminide Fe2Al5 which forms in a considerable amount within an alloy of nominal composition Fe(65)Mn(15)Cr(12) Al(5)Si(2)C(1) (per cent by weight). Although the Mn3AlC carbide is, like Fe3AlC, a perovskite carbide, manganese does not appear to favour the formation of the perovskite carbide. Because of the relatively low sintering temperature (700° C), for a large portion of the samples equilibria conditions are not always reached. Furthermore, due to this temperature, iron is in the ferritic state.
