dc.description.abstractThis research explores the effect of chromium additions (5% and 10%) on the corrosion behavior of Fe-22Mn-0.6C TWIP (Twinning Induced Plasticity) steel in 0.1 M Na2SO4 solutions at 25°C. Microstructures were characterized by using light microscopy and X-ray diffraction (XRD). Corrosion products were analyzed via scanning electron microscopy (SEM) and Raman spectroscopy. The results indicate that chromium enhances corrosion resistance by promoting the formation of protective oxide layers, although variations in chromium content significantly affect the uniformity and stability of these layers. A comprehensive electrochemical analysis, including open circuit potential (OCP) and electrochemical impedance spectroscopy (EIS), revealed the benefits of Cr alloying in improving the passivation behavior of TWIP steels. The study highlights the potential of optimized Cr content to balance mechanical strength and corrosion resistance in TWIP steels for industrial applications.
