For a Thermo-Calc database, is it possible to view the equation/parameters of the Gibbs free energy models?

I am not sure about TC-Python but in console mode, you can access the Gibbs energy equations directly using the Gibbs Energy System (GES) module. In case you need the details about a particular phase ...

Is it possible to analytically solve for a particular phase region of a CALPHAD database? (instead of guessing and checking)

if you had access to the database equations for a given alloy system, could you analytically solve (and thus solve quickly) for the conditions (i.e., temperatures and compositions) that would produce ...

Thermo-calc: Calculate precipitation driving force by parallel tangent construction

Thermo-Calc's DGM is the normalized parallel tangent driving force per mole of components. To be able to compute the driving force of a phase, it must be set to &...

What information about a crystalline solid material goes into calculating phase diagrams in Thermo-Calc, and how?

Enthalpy and entropy are the temperature dependent terms in free energy from which enthalpy is a dominant term mainly at lower temperature and entropy is dominant at higher temperature (because ...

How to get order constitution data for single equilibrium calculation in Thermo-Calc's TC Python module?

I don't have access to TC-Python, so I can't offer advice on how to use the API specifically. This is more of a workaround than a direct way to get Thermo-Calc to tell you whether the phase is ordered ...

Thermo-Calc: how to suspend specific composition sets?

Thermo-Calc creates new composition sets from the global minimization process and you cannot, to my knowledge, have direct control of preventing certain composition sets from being created. Disabling ...

How to calculate t-zero temperature using Thermo-Calc- Python (TCPython) for multiple alloys?

I have faced a similar issue and it seems that something happens while calling calculate(). I think it may be because when you use the same single equilibrium calculation for determining the Gibbs ...
