Thermo-Calc Software

Learn how to make thermodynamic calculations, diffusion simulations and precipitation simulations using Thermo-Calc software.

Our videos will also teach you how to install Thermo-Calc and will keep you up-to-date on the latest releases and additions to the software and the newest thermodynamic databases and diffusion databases.

Thermo-Calc Software specialises in developing software and databases for computational materials engineering, also known as computational thermodynamics. Our software and databases are used by organisations around the world for both fundamental research and applied research, such as design of new alloys, optimisation of processing conditions, failure analysis and much more.

Avoid defects in the Powder Bed Fusion process with printability maps, now available in the AM Module in Thermo-Calc.

During the Powder Bed Fusion process in additive manufacturing, three possible defects can occur based on the power and scan speed: keyholing, lack of fusion, and balling. When manufacturers work with a new material, they create printability maps, also called process maps, to identify the processing conditions that are optimal to minimize the likelihood of these defects.

These maps are often created experimentally, which can be both expensive and time-consuming. But now they can be simulated in the AM Module in Thermo-Calc for any alloy system. With printability maps, manufacturers can reduce trial-and-error experimentation, minimize defects, and enhance overall print reliability.

This video will show you how to simulate a CCT diagram for gamma prime precipitation in a Ni-Al-Cr alloy, using the Precipitation Module (TC-PRISMA).

The continuous cooling transformation, or CCT calculation type allows users to make a calculation which maintains the same cooling rate for the entire time.

Introducing Thermo Calc 2024b

Watch this video to learn how to calculate the driving force of the M7C3 carbide and plot the results as a heat map and contour plot, in the Graphical Mode in Thermo-Calc. The Driving force is the change in Gibbs energy when forming a new phase (ΔG). And it is crucial in determining whether or not a phase is likely to form.

This calculation is based on example T_09, which is included with your software. The calculation can be run by anyone with a license for Thermo-Calc, including the free Educational Package.
