Predicting thermodynamic properties in Ti–Al binary system by FactSage

The results of predicting thermodynamic properties in Ti–Al binary system were shown in this paper. The activity of titanium and aluminum in titanium–aluminum alloys were calculated using FactSage thermochemical software and databases. The activity of Ti and Al as a function of titanium concentration was calculated in the temperature range between 1773 K and 2273 K. The activity–temperature (1.0 > XTi > 0.1) relationships for Ti–Al alloys for a temperature ranges between 1773 K and 2273 K were calculated, too. Some predicting thermodynamic results were compared to available experimental results. A good agreement has been noticed.
