Abstract
The model of Miedema semi-empirical can be considered as a promising technique for the estimation of the thermodynamic variables of solid solution that classified into binary and ternary Fe-Al-Cr and Fe-Al-Cu based systems. For the latter to be conducted, A recently delevolped software called MAAT (materials Analysis Applying Thermodynamics ) was used in the current work to calculate the thermodynamic characteristics of the "binary and ternary" systems. The results demonstrated that the values of the Gibbs free energy concerning the binary systems of the solid solution of each of Fe-Al, Fe-Cr, Al-Cr, and Al-Cu were seen to be negative and lower than that of the ideal Gibbs free energy, except with Fe-Cu that was positive. For ternary system (Fe-Al-Cr and Fe-Al-Cu), the Gibbs free energy level were noticed to be negative across most of the composition extent. This is suggesting that, there were driving forces to reach the solid solution from pure Fe, Al, Cr and Cu powders lies within the full extent of composition.
