Thermo-Calc Applications to Casting
- Solidus and liquidus temperatures
- Fraction solid curves (under equilibrium and non-equilibrium conditions)
- Micro-segregation predicted by Scheil solidification simulations, including partial equilibrium in the liquid and solid for elements identified by the user as fast-diffusers | Example Calculation
- Latent and specific heat
- Cp and apparent Cp
- With databases that include molar volume data, both density and relative length change can be predicted
- Thermal expansivity
Diffusion module (DICTRA) Applications to Casting
- Micro-segregation during solidification as a function of cooling rate (Thermo-Calc calculations based on Scheil do not consider cooling rates)
Example Calculation: Microsegregation during Solidification
See an example which uses Thermo-Calc together with the add-on Diffusion module (DICTRA) to investigate and predict microsegregation (solute redistribution) during solidification. The example includes a comprehensive analysis of the calculation and a calculation file which you can download and run in Thermo-Calc.

PAPER: Continuous Casting of High Carbon Steel: How Does Hard Cooling Influence Solidification, Micro - and Macro Segregation?
This open access paper investigates why hard secondary cooling significantly reduces macro-segregation. The solidification of high carbon tire cord grade C80D cast as a 150x150 mm billet is calculated using the proprietary SMS Group solidification simulation package CHILL using steel properties calculated with the Thermo-Calc Software package and TCFE steels database.
