Thermo-Calc 2024.2: The Gold Standard in Computational Thermodynamics
Thermo-Calc 2024.2 is the industry-leading software platform for computational thermodynamics and materials design using the scientifically robust CALPHAD (Calculation of Phase Diagrams) method. It empowers materials scientists, metallurgists, and engineers to perform sophisticated thermodynamic calculations to predict phase stability, equilibrium, and material properties in complex multi-component systems—essential for developing new alloys, optimizing heat treatments, and solving manufacturing challenges.
Core Function: Predictive Thermodynamic Modeling
The software’s engine performs Gibbs energy minimization to determine the most stable phases and their compositions under user-defined conditions (temperature, pressure, composition). This replaces guesswork with quantitative predictions about material behavior.
Key Functions:
-
Phase Diagram & Property Diagram Calculation: Generates binary, ternary, and multi-component phase diagrams, as well as property diagrams (e.g., phase fraction vs. temperature), providing a complete map of material stability.
-
Equilibrium and Scheil Solidification Simulation: Calculates both full thermodynamic equilibrium and non-equilibrium Scheil solidification to predict microsegregation and secondary phase formation during casting and welding.
-
Database-Driven Calculations: Leverages a suite of critically assessed thermodynamic databases (TCB for steels/Fe-alloys, TCS for superalloys/Ni-alloys, MOB for mobilities, etc.) for accurate, real-world material predictions.
-
Materials Property Prediction: Calculates key thermochemical and thermophysical properties, including heat capacity, enthalpy, entropy, and activity, supporting both design and process simulation.
