Analysis of Solubility of Carbides, Nitrides, and Carbonitrides is Steels Using Methods of Computer Thermodynamics: I. Description of Thermodynamic Properties. Computation Procedure

摘要

Review of modern approaches to the description of the Gibbs energy of multicomponent phases in metal alloys is given. Application of the CALPHAD* method for the description of thermodynamic properties of multicomponent phases is described. Problems of calculations of phase equilibria in multiphase multicomponent systems and methods of their solution are considered. A method of calculation of phase equilibria in such systems has been developed. This method is laid into the basis of a computer program for the calculation of phase equilibria in the iron-based alloys, which was used to analyze the solubilities of carbides, nitrides, and carbonitrides in steels.
