How to get order constitution data for single equilibrium calculation in Thermo-Calc's TC Python module?
I know that it is possible to get order constitution data for phases when using Thermo-Calc's GUI (e.g. to get "BCC_B2 DISORD" instead of just "BCC_B2") for a single equilibrium ...

Why does Thermo-Calc one axis equilibrium calculation get stuck in never ending loop?
I've been trying to run a Thermo-Calc one axis equilibrium calculation on some quaternary alloys in the TCHEA4 database. Most of the calculations work fine, but for some alloys it gets stuck in a loop ...

For a Thermo-Calc database, is it possible to view the equation/parameters of the Gibbs free energy models?
I want to get the equations that model free energy for a given phase in a given alloy system (see attached image). I do not just want to get values of free energy for specific compositions. Is it ...

What thermodynamic data is collected in order to build a CALPHAD model?
To build a model using the CALPHAD approach, i.e. Gibbs free energy as a function of composition and temperature, typically taking the form of a Redlich-Kister polynomial, what kind of thermodynamic ...
