“…A significant increase in the service properties of the metal of workpieces obtained in the foundry can be achieved by the implementation of the modification technology. In this process, nucleation is carried out by introducing solid refractory particles into the molten metal [1][2][3][4]. Most often, ultradispersed powders of previously synthesized refractory compounds of a number of transition metals with a dispersion of 0.01-0.1 microns are used as solid particlesinoculators.…”

The efficiency of the solid-phase activation of modifying complexes has been evaluated. It is shown that such preliminary treatment of refractory particles leads to a significant increase in the diffusion coefficients in the matrix of the metal-ultrafine powder complex. The introduction of modifying complexes that have undergone solid-phase activation into liquid nickel increases the degree of supercooling of the melt and reduces the grain, which characterizes a high degree of intensity of the action of inoculators. In this case, the most intense effect is exerted by the addition of the TiCN-Ni and TiCN-Ti complexes that have undergone solid-phase activation.

“…Особенно эффективно устраняется транскристаллизация при использовании комплексного модификатора, в состав которого входят химически активные элементы (Ca, Al), поверхностно-активный висмут и карбидообразующий бор [3,4]. Совместное действие различных по своим свойствам элементов усиливает эффект, получаемый при введении в сталь каждого из них в отдельности.…”

A theoretical analysis of the influence of carbon content in the steel and nature of macrostructure on segregation of impurities in the crystallization process were made. It is shown that increase of carbon content and transgranular macrostructure creation degree of segregation is being increased. A comparison of sulfur segregation in the ingot with equiaxial and transgranular structure was carried out and the theoretical points were confirmed.
