Аннотация
The surface tension and density of Fe–C-containing melts with SiC and TiC0.8N0.16O0.04 nanosized phases have been investigated and show that the presence of SiC leads to a slight increase in the surface tension and the introduction of TiC0.8N0.16O0.04 leads to its decrease. It is shown that coefficients ∂σ/∂Τ of these melts without and with nanophases are positive. It is found that, with the introduction of nanophases into the metal, the density of the melts decreases and loosening increases. The composition of heterogeneous nonmetallic inclusions depends on nanophases: the introduction of SiC reduces the oxygen content in them, TiC0.8N0.16 O0.04 increases it, and the composition of homogeneous inclusions depends on the interaction of nanophases with sulfur and leads to a decrease in the element in them.
