Thermo-Calc is a powerful, integrated software suite for computational materials engineering and thermodynamics. It is the industry standard for performing thermodynamic and phase equilibrium calculations, which are fundamental to understanding and designing alloys, steels, ceramics, slags, and other materials.

The software is built around extensive, critically assessed thermodynamic databases (like TCFE for steels, TCNI for Ni-superalloys, MOB for diffusion/mobility). It allows users to calculate phase diagrams (binary, ternary, multi-component), simulate phase transformations, predict material properties, and model processes like solidification, heat treatment, and corrosion.

Understanding Thermo-Calc Versioning: "2025b"

The version name "2025b" follows Thermo-Calc Software's standard release pattern:

• 2025: The release year.

• b: Stands for the second major release of that year. Thermo-Calc typically has two main releases annually: an "a" release (e.g., 2025a) around mid-year and a "b" release (e.g., 2025b) towards the end of the year.

Each release (both "a" and "b") typically includes:

• New and Updated Databases: This is often the primary update—adding new systems, improving existing models with new experimental data, and expanding into new material classes.

• Software Enhancements: New features, improved graphical interfaces (in the Thermo-Calc Console or add-on modules like PRISMA), bug fixes, and performance improvements.

• New Functionality: Introduction of new calculation types or integration of additional modules.
