abstract: On the basis of economic and lower density considerations, Fe-Ai-Mn alloy could be a good candidate for replacing some of stainless steel. Aluminium and manganeses. Are used to replace the expensive alloying element in convetional Fe-Cr-Ni system. The aim of the research is to investigate harden ability and corrosion resistance of Fe-7,AI-15Mn in the NaCIAnd H2SO4. Thirty five kilograms of Fe-Al-Mn were prepared from medium carbon steelscrap, high purity alumunium and Fe-Mn medium C, The alloy was prepared in an induction furnace under an argon armosphere. Jominy test and microstructure were examined. The corrosionrate were carried out with three-electrode polarization in 0.5% NaCI and 0.05M H2SO4. Thecorrosion type and the morphology of oxide scale were examined by optical microscopy andscanning electron microscope (SEM). Corossions products were examined with EDS/EDAX. Theoptical micrograph show that as cast Fe-7,5AI-15Mn alloy has austenite and ferrite microstructure.The result of Jominy test shows that Fe-Al-Mn alloy non-harden able. The result ofcorrosion testing showed that the alloy more resistance in NaCI than in H2SO4 solution. Opticalmicrograph and SEM analysis indicated that corrosion form is general corrosion and there is notrend toward intergranular attack.
