About the CCT Diagram Property Model

The CCT Diagram Property Model, available with the Property Model Calculator and the Steel Model Library, can be used to calculate a Continuous-Cooling-Transformation (CCT) diagram, with a One Axis calculation on Log10(cooling rate[K/s]). This Model calculates the kinetics of concurrent transformation of austenite into ferrite, pearlite, bainite, and martensite. The algorithms and parameters for ferrite, pearlite, bainite, and martensite are the same as in their individual Property Models (Ferrite, Pearlite, Bainite, Martensite Temperatures, and Martensite Fractions), but the competitive occupation of prior austenite grain boundaries and bulk volume is handled in the CCT Diagram Property Model.

To run calculations with the Steel Models requires a valid maintenance license plus licenses for both the TCFE (version 9 and newer) and MOBFE (version 4 and newer) databases. Also see our website to learn more about the Steel Model Library and other related examples.

The input parameters are entered on the Configuration window for the Property Model Calculator. There are also settings on the Plot Renderer where you can choose from the available and relevant axis variables.

See CCT Diagram Property Model Settings for details.
