Effect of quaternary alloying elements Mn, Cr, Ni and Ti on structure and properties of Fe 3 Al-based alloy containing about l wt.% carbon have been investigated. Four different alloys were prepared. The composition of the quaternary alloying element was proposed to be ~4 wt.% and was substituted for iron. Processing of Fe-16Al-4.1Mn-1.0C, Fe-16.5Al-3.5Cr-0.94C, Fe-16Al-4.0Ni-0.9C and Fe-15.6Al-2.8Ti-1.0C alloys through a combination of air induction melting with flux cover (AIM) and electroslag remelting (ESR) yields a sound ingot free from macro and microporosity with very low sulphur, oxygen and nitrogen. This process route also exhibited excellent recovery of alloying elements. As-cast alloys were examined using optical microscopy, X-ray diffraction, electron probe microanalyses (EPMA) and scanning electron microscopy (SEM) in conjunction with energy dispersive X-ray analysis to understand the microstructure of these alloys. The as-cast ESR ingots of alloys containing Mn, Cr and Ni exhibited a two-phase structure of Fe 3 AlC 0 . 5 precipitate in the Fe 3 Al-based matrix. Both phases exhibited considerable amount of solid solubility for Mn, Cr and Ni, whereas the alloy containing Ti exhibited a three-phase microstructure of TiC particles and Fe 3 AlC precipitates in the Fe 3 Al-based matrix. This alloy has also exhibited very low solubility of Ti in the Fe 3 Al-based matrix and no solubility in the Fe 3 AlC precipitates. Several microcracks were observed in the as-cast ESR ingots of the high carbon Fe 3 Al alloy containing Ni and tensile tests could not be carried out for this composition. Tensile and creep tests were performed on the high carbon Fe 3 Al alloys containing Mn, Cr and Ti in the as-cast condition. No improvement in room temperature tensile strength and inferior high temperature strength and creep properties was observed by the addition of quaternary alloying elements.
