Materials analysis applying thermodynamic (MAAT) software: A friendly and free tool to analyze the formation of solid solutions, amorphous phases and intermetallic compounds

The main characteristics of the software are: i) calculation and plotting Gibbs free energy of mixing curves of random solid solutions, amorphous and intermetallic compounds, ii) calculation and plotting the activity of components in solid solutions, and iii) analysis of the effect of additional terms over the Gibbs free energy of mixing of random solid solutions, such as centrifugal field, grain size and dislocations.

In this work, the thermodynamic calculations performed with MAAT are compared with experimental data in four cases: formation of solid solution (Cu-Mo-Cr system), formation of amorphous phase (Ti-Ta-Sn system), formation of intermetallic compound (Cu-Nb-Co system) and effect of centrifugal field on formation of solid solution (Cu-Cr system). For all systems analyzed, the calculations made using MAAT gave results that are comparable with experimental data.
