In the second part, the method for deriving the Gibbs free energies incorporating the ab initio calculations is In the third part the application to predict thermodynamic properties of compound phases is discussed. The The CALPHAD method has recently been extended to model additional thermophysical properties, such as electric resistivity, thermal conductivity, surface tension, viscosity and more, which are needed to simulate the mass and heat transfer in material manufacturing processes, such … CALPHAD method basics The simplest way to have a complete description of the thermodynamic behavior of a system at fixed temperature, pressure and chemical composition, is to know – i.e. to be able to calculate – its Gibbs energy The CALPHAD method, on the other hand, is based on the minimization of the free energy of the system and is, thus, not only completely general and extensible, but also theoretically meaningful. The experimental determination of phase diagrams is a time consuming and costly task.
