Coarsening Property Model Settings

Coarsening is a General Property Model available when using the Property Model Calculator in Thermo‑Calc and it calculates the coarsening rate coefficient K (m3/s) of a spherical precipitate phase in a matrix phase.

The output using this Model is the coarsening rate coefficient [m3/s] for the precipitate phase and the interfacial energy [J/m2] between matrix and the precipitate phase.

This Model requires that the thermodynamic database used includes descriptions of molar volume of the matrix and precipitates phases as well as a kinetic database with mobilities for the matrix phase.

About the Coarsening Property Model

For an example, see PM_G_02: Coarsening and Interfacial Energy.

Configuration Settings

The settings are found on the Property Model Calculator when Coarsening is selected under General Models.

When working in the Configuration window, click the Description tab for more information about the Model.

For the details about the Condition Definitions, Calculation Type, Timeout in minutes, Parallel Calculation, and other calculation associated settings, see Property Model Calculator: Configuration Window Settings.

Choose a Matrix phase.

Choose a Precipitate phase to calculate its coarsening rate. Click the Button: plus sign to add something Add phase button to add another Precipitate phase. Click the Remove minus sign button Remove phase button to remove a phase.

Plot Renderer Settings

Plot Renderer and Plot Renderer: Configuration Settings

When setting up your calculation on the Plot Renderer and/or Table Renderer, the following axis variables are available for the conditions defined on the Property Model Calculator.

When selecting quantities on the Plot Renderer or Table Renderer, the quantity names include an abbreviated name for the Property Model it is associated to. This is useful in particular when you are calculating two or more Property Models that share names for the quantities. The short name identifying the specific Property Model is included in parentheses after the name of the quantity. Below are the full and abbreviated names for each Property Model.

For a list of the abbreviations associated to a Property Model, see Result Quantities: Property Model Abbreviations.

Select from these plot quantities:

  • Temperature
  • Coarsening rate coefficient Ni [m3/s] for the precipitate phase.
  • Interfacial energy Ni [J/m2] for it to be between the matrix and precipitate phase.
