Parameters of the Microheterogeneous Structure of Liquid 110G13L Steel

Original experimental data on the viscosity, density, surface tension, and electrical resistivity of liquid 110G13L steel are presented. The results from measurements are discussed in terms of the concepts of the microheterogeneity of metal melts. The relationship between the structure-sensitive properties of metal melts-viscosity, density, surface tension, and electrical resistance-is studied in the context of exploring the conditions for the existence of microheterogeneity. Based on experimental data, a conclusion is drawn about the laws governing the evolution of microheterogeneity upon a change in the temperature of a melt, and a numerical estimate is made of the parameters of the microheterogeneous structure of the liquid steel, particularly the sizes of dispersed particles.
