Thermodynamic Analysis of the Formation of Nonmetallic Inclusions in 40KhGM Steel with Various Sulfur Contents

摘要

The interaction between elements of multicompo-nent metallic melts is dependent of many factors. Therefore, it is difficult to study these interaction pro-cesses, which, in addition, occur at high temperatures. At the same time, a thermodynamic analysis of these interaction reactions permits one to determine the pat-tern of phase equilibria in a certain system and to follow the precipitation of excess phases during cooling and solidification of a metallic melt.
