This paper looks at the effect produced by oxygen on oxide, oxysulphide and sulphide inclusions and how they form in medium-carbon and lowalloy steels. The results of a laboratory study that looked at specimens made of steel 45, revealed a negative role of aluminium used as a deoxidizer, as it causes the sulphide inclusions arrange themselves at grain boundaries. In 38KhN3MFA steel specimens deoxidized with silicocalcium, the sulphide inclusions have better arrangement as they are located in the grain, due to the doping effect of the deoxidizer. The authors analyze how the level of oxidation (vacuum degassing) in and the type (basic or acidic) of the 38KhN3MFA steel can affect the mechanical properties of forgings for power engineering application.

The reported study was funded by RFBR according to the research project № 16-38-00007 мол_а_дк.
