Driving Force Property Model Settings

Driving Force is a General Property Model available when using the Property Model Calculator in Thermo‑Calc and it calculates the thermodynamic driving force for a phase divided by RT.

For an example, see PM_G_03: Driving Force and Interfacial Energy.

Configuration Settings

The settings are found on the Property Model Calculator when Driving force 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, the single phase region to start in. Select Any phase to use the phases that take part of the initial equilibrium or choose a specific phase.

Choose a Precipitate phase to calculate its driving force. Click the plus Add quantity and minus Remove quantity buttons to add or remove Precipitate phases as needed.

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:

  • Composition
  • Interfacial energy Ni [J/m2]
  • Driving force per mole and then choose a unit: Joule, Calorie, Electron volt, Gigajoule, Watt hour, or Kilowatt hour.
  • Normalized driving force
