Thermo‑Calc Software

Thermo-Calc Software develops computational tools used to predict and understand materials properties, allowing you to generate computational materials data without costly, time-consuming experiments or estimations based on the limited data available.

Thermo-Calc can be used to fill the gaps in material property data and make predictions of material behavior throughout the materials life cycle. With Thermo-Calc, you can make better decisions about your products and improve your material processing conditions with accurate, reliable materials data.

The Thermo‑Calc software (also referred to as the Thermo‑Calc program or the software to distinguish it from the company name) is used to perform thermodynamic calculations. It can calculate complex homogeneous and heterogeneous phase equilibria, and then plot the results as property diagrams and phase diagrams.

The software fully supports stoichiometric and non-ideal solution models and databases. These models and databases can be used to make calculations on a large variety of materials such as steels, nickel, aluminum, magnesium, titanium and titanium aluminide-based alloys, high entropy alloys, copper, slags, salts, ceramics, solders, polymers, subcritical aqueous solutions, supercritical electrolyte solutions, non-ideal gases, and hydrothermal fluids or organic substances. The calculations take into account a wide range of temperature, pressure, and compositions conditions.

There are several resources available on our website to help you learn how to use Thermo‑Calc and other Add-on Modules. Go to the Getting Started Guides page and choose one of the guides that provides new users an introduction to setting up simple calculations in Graphical Mode. The information there is also in this help documentation.

The Thermo‑Calc program also includes Add-on Modules:

The Diffusion Module (DICTRA) is used to simulate diffusion controlled transformations in multicomponent systems.

The Precipitation Module (TC-PRISMA) is used to simulate diffusion controlled multi-particle precipitation process in multicomponent and multiphase alloy systems.

The Process Metallurgy Module is used to set up calculations for steel and slag used in steel making.

There are also specialized Property Models available with the Nickel Model Library, Noble Metal Alloys Model Library, Steel Model Library, and Titanium Model Library.

The Additive Manufacturing (AM) Module is used to better understand the laser powder bed fusion (LPBF) process by predicting the temperature distribution and melt pool geometry as a function of process parameters.

There are over 40 high quality kinetic, properties and thermodynamic databases for use in our software. Each database is developed for a specific materials system or application, and all databases are developed using the proven CALPHAD methodology.

The quality of the predictions in Thermo-Calc is strongly dependent on the quality of the databases because they provide the data for the calculations. This makes the databases as important, if not more so, than the software itself.

Thermo-Calc Software has long experience in the field of database generation using the proven CALPHAD methodology. We employ a highly qualified team of people working on database development internally and through international collaboration projects. With our kinetic, properties, and thermodynamics databases, you can rest assured that you are working with the most advanced CALPHAD databases available.

The help contains the database content you can find on the website, which includes the technical information and examples.
