Thermodynamic Assessment as a Tool for Modeling Interactions at the Interface Between Ceramic Filter and Melt

Abstract

AbstractThe chapter will focus on the thermodynamic database development relevant to modeling the interactions between filter materials, coatings, and inclusions in steel and Al-alloy. The CALPHAD approach is applied to develop thermodynamic databases, i.e. the available phase diagram data and experimental thermodynamic values are used to optimize the parameters describing the Gibbs energy of phases which can exist in the system. Thermodynamic description of multicomponent systems is the basis for more advance simulation of technological processes. In the chapter, the fundamentals and theory of thermodynamic modeling will be discussed in detail, and the most important results obtained will be presented. Examples of the thermodynamic calculations applied for solution of technological problems will be discussed.
