Özet
Ferrotitanium is widely used in alloying stainless steels to enhance their strength, corrosion resistance, and high-temperature resistance. Ferrotitanium's advantages over pure titanium - such as better solubility in the liquid steel bath and lower cost - have made it the preferred choice in stainless steel alloying. In this study, it was aimed to produce ferrotitanium alloy through the metallothermic reduction of Fe2O3 and TiO2. The system's thermodynamic modeling was performed using HSC Chemistry 6.12 and FactSage 7.1. The experimental studies investigated the effect of using aluminum as a reductant with varying stoichiometries on the total metal recovery yield, hardness, and microstructure. Atomic absorption spectrometry (AAS), optical microscopy, scanning electron microscopy (SEM), X-ray fluorescence spectrometry (XRF), and hardness measurement techniques were employed in characterization studies. The results of the experimental studies showed that the highest metal recovery yields were obtained with 105 % stoichiometric aluminum as 97.9 % for Fe and 100 % for Ti.
