About the Steel Model Library Property Models

These Steel Models are available with the Property Model Calculator. The following are available with the Steel Model Library.

Also see Steel Library CCT Diagram Template, Steel Library TTT Diagram Template, Plot Type: CCT Mode, and Plot Type: TTT Mode.

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.

For the Ferrite, Bainite, and Pearlite Property Models, it is also useful to review the Recommended Composition Ranges for Steel Models.

The Bainite Property Model describes the thermodynamics and isothermal kinetics of bainite transformation from austenite. In this Model, bainite is modeled as ferrite or a ferrite-cementite mixture.

See About the Bainite Property Model and Bainite Property Model Settings for background theory and input parameter details.

The CCT Diagram Property Model calculates the concurrent transformations to ferrite, pearlite, bainite, and martensite under continuous cooling conditions and is used to construct a continuous-cooling-transformation (CCT) diagram.

See About the CCT Diagram Property Model and CCT Diagram Property Model Settings for background theory and input parameter details.

The Critical Transformation Temperatures Property Model calculates critical transformation temperatures for steels.

See About the Critical Transformation Temperatures Property Model and Critical Transformation Temperatures Property Model Settings for background theory and input parameter details.

The Ferrite Property Model calculates the thermodynamics and isothermal kinetics of proeutectoid ferrite forming from austenite in hypoeutectoid steels.

See About the Ferrite Property Model and Ferrite Property Model Settings for background theory and input parameter details.

The Martensite Fractions Property Model calculates the fraction of athermal martensite based on available driving force.

See About the Martensite Fractions Property Model and Martensite Fractions Property Model Settings for background theory and input parameter details.

The Martensite Temperatures Property Model calculates the martensite start (Ms) temperature based on modeling of the transformation barrier. Martensite half and finish temperatures are also given according to the Martensite Fractions Property Model.

See About the Martensite Temperatures Property Model and Martensite Temperatures Property Model Settings for background theory and input parameter details.

The Martensitic Steel Strength Property Model calculates the strength and/or hardness of martensitic steels.

See About the Martensitic Steel Strength Property Model, Flow Stress, and Martensitic Steel Strength Property Model Settings for background theory and input parameter details.

The Pearlite Property Model calculates the thermodynamics and kinetics of pearlite formation from austenite during isothermal heat treatment.

See About the Pearlite Property Model and Pearlite Property Model Settings for background theory and input parameter details.

The TTT Diagram Property Model calculates the concurrent transformations to ferrite, pearlite, bainite, and martensite under isothermal conditions and is used to construct a time-temperature-transformation (TTT) diagram.

See About the TTT Diagram Property Model and TTT Diagram Property Model Settings for background theory and input parameter details.
