FactSage 8.3 is a major release of the leading integrated software platform for computing thermodynamic equilibrium and phase diagrams, developed collaboratively by Thermfact/CRCT (Montreal, Canada) and GTT-Technologies (Aachen, Germany). it builds on the Calphad method to model complex multicomponent, multiphase systems across materials science, metallurgy, geology, chemistry, and environmental engineering. FactSage supports over 35,000 pure substances and thousands of solution phases from extensive databases, enabling predictions of phase stability, reaction paths, and thermochemical properties under varying conditions like temperature, pressure, and composition.
This version emphasizes enhanced Python integration, improved visualization tools, and updates to core modules for better performance in industrial applications such as alloy design, process optimization, and battery materials research. which includes further refinements like advanced kinetic modeling—upgrading is recommended for users on active maintenance.
