Abstract
Temperature dependences of kinematic viscosity of liquid stainless steel have been investigated. The existence of critical temperatures, heating above which leads to irreversible changes in the structural state of the melt, has been substantiated. Directed thermal influence on the melt based on its transition to another structural state allows to carry out melt solidification in various conditions, to regulate morphology and magnitude of structural composition and to develop scientifically grounded melting modes. A physical model of the structure of liquid stainless steels is proposed. The analysis of the obtained temperature dependences shows that liquid stainless steels can be in different states, the temperature fields of existence of which partially overlap.
