“…According to the results of the most recent detailed studies [5,6], it has been established that under certain modes of ladle treatment and continuous casting of modern structural steels oxide inclusions are formed based on SiO 2 -Al 2 O 3 , SiO 2 -Al 2 O 3 -CaO, MnO-SiO 2 , and SiO 2 -Al 2 O 3 -MnO compositions and others, which in many respects determine the resulting structural state and complex of metal properties. Among them are vitreous inclusions.…”

“…As a result, when modern metallurgical technologies are implemented, the formation and evolution of nanoscale objects in the steels takes place already at the stage of processing the metallic melt [7]. There are all the prerequisites for using them instead of or in addition to phase precipitates and structural components formed due to the use of costly alloying and microalloying components, which play a key role in achieving the structural state and high complex of steel properties [1,4,6,7].…”

The study of regularities of the formation and evolution of nonmetallic inclusions and phase precipitates in modern structural steels has been carried out. It has been shown that the formation of several types of complex nonmetallic inclusions results in a substantial increase in the complex of steel properties and neutralizing the negative influence of impurities while a reduction in costs. An even more significant improvement in the properties of steel can be achieved by controlling the characteristics of carbide, carbonitride, and other types of phase precipitates. Herewith, ferritic steels are the most promising. The previously unreachable complex of indicators of difficult to combine service properties of these steels has been achieved by the formation of a homogeneous fine-dispersed microstructure and a volumetric system of primarily interphase precipitates. Based on established principles, effective technologies for the production of a wide range of various types of steels have been developed.
