GTT was represented at the TMS 2019! The TMS (https://www.tms.org/TMS2019) is a huge annual conference, organized by the Minerals, Metals and Materials Society in the United States. This year the conference took place in San Antonio, Texas. Dr. Stephan Petersen gave a presentation at one of the symposia of REWAS 2019, which focuses on Manufacturing […]
A customer has asked me: “Is it possible to export/import data to and from FactSage? For instance, I would like to do a series of calculations for different initial chemical compositions of the system and it would be very useful to import all the compositions automatically from an Excel table into FactSage”. Yes, it is

Ex Mente Technologies and GTT-Technologies are excited to announce the first commercial release of ChemAppPy! ChemAppPy is a Python package that makes ChemApp, the thermochemistry library developed by GTT-Technologies, available in Python 3.6+. It includes additional tools that make thermochemical calculations easier and quicker to do. GTT are the original developers of ChemApp, a powerful
In a series of posts, we will focus on the relation between phase diagrams, Gibbs energy functions and activities. Let us begin with the Al-Cu phase diagram at a temperature of 500 °C. In this blog post we will work exclusively with the FactSage Education Package. Let us suppose we have generated an Al-Cu phase-diagram

A customer has asked me: “How can I include an experimental point on a figure generated in FactSage ?”. The procedure is relatively simple. Suppose that you have generated a curve in FactSage like the one below. Representing the Molar Gibbs Energy of the γ phase in the Fe-C system at 1000°C as a function

I have been asked by a potential customer: “Do I need the Fact Pure Substances or SGTE Pure Substances database?” The answer is: It depends. The two databases are both collections of (normally published) thermochemical data. The Fact Pure Substances database FactPS is maintained by our co-developer of FactSage, Thermfact/CRCT, Polytechnique Montreal. It is generally
What is the difference between Fact Pure Substances and SGPS databases? Read More »
It is a common misconception that thermodynamic calculations can only be used for processes that are in equilibrium. In fact, there is a lot to learn from an Integrated Thermodynamic Databank System like FactSage even if you are far away from equilibrium! As example we consider the popular Fe-C system: If you choose all phases

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. Phase Diagram permits the calculation of phase diagram sections for systems with any number of components. Components can be elements, compounds or even arbitrary compositions. For a phase diagram calculation, first the components of interest have to be defined. Then, the possible

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. In the Equilib module, global Gibbs energy minimization is used to determine the equilibrium state of a complex chemical system defined by its chemical composition, temperature and pressure. Equilib is easy to use: First, the chemical system has to be defined
