description: Topic of the bachelor's thesis: "Influence of non-metallic inclusions on the corrosion resistance of duplex stainless steels".In this study, the effect of different types of non-metallic inclusions (NMIs) on the corrosion resistance of duplex stainless steel was examined. Melting and casting of a commercial grade of duplex stainless steel with various deoxidation options â aluminum wire and rare-earth metals was carried out. Using the methods of optical and electron microscopy in combination with electrochemical studies, the influence of NMIs on the corrosion resistance of duplex stainless steels has been studied. The most dangerous types of NMIs initiated pitting corrosion in duplex stainless steels have been determined and recommendations to minimize them have been developed. The transformation of NMIs after deoxidation by various elements has been studied. It is shown that, using various deoxidation technologies, it is possible to obtain both NMIs that are dangerous and relatively safe in terms of corrosive activity. A thermodynamic assessment of the corrosion activity of NMIs has been carried out, which makes it possible to rank the inclusions according to the degree of danger of pitting on them. The results of this assessment can be used in the development of technology for the deoxidation of DSSs in production.
