Abstract:
The present report is the summary of the experimental studies on the production of ferroalloys and iron-based alloys, which have been conducted in the laboratories of Macro to Nano Research Team (MtNT, Yücel’s Group) at Istanbul Technical University (ITU, Turkey) – Metallurgical and Materials Engineering Department in the last decade. Ferromolybdenum, ferrochromium, ferronickel, and iron-based alloys with alloying elements (Mo, Ni, Cr, etc.) were produced through different reduction processes (metallothermic and carbothermic) starting from different reactant materials such as mill scale, hematite, magnetite, NiO, Cr2O3, chromic acid, and MoO3. The effects of different stoichiometric amounts of reactants and reductant powders were investigated for the production of unalloyed Fe. While, different amounts of metal oxide ratios and their effects on metal recoveries, compositions, and microstructure of final alloys were studied during Fe-based alloys production, raw materials and produced alloys and slags were characterized by using chemical analysis methods (AAS, ICP), X-ray diffraction spectrometry (XRD), X-ray fluorescence spectrometry (XRF), and scanning electron microscopy (SEM/EDS) techniques.
