Abstract
In this work, a thermodynamic analysis of the Al-C-Fe system is carried out covering a wide tem-perature range. The sublattice model of Hillert for the solution phases and the Redlich-Kister-Mug-gianu formalism for the interaction parameters are used. The binary and ternary interaction parameters and the Gibbs energies of formation of the carbides are obtained by optimization of the thermochemical and the phase diagram data. The results include a liquidus projection, details of the four-phase invariant reactions, a reaction table, and eight isothermal sections covering the tempera-ture range from 2000 °C to 800 ’C.
