Steel and Fe-Alloys Databases

TCFE15 is a thermodynamic and properties database with applications to a variety of steels and Fe-based alloys, such as stainless steels, high-speed steels, tool steels, high-strength low alloy (HSLA) steels, cast irons, corrosion-resistant high strength steels, low-density steels, and also cemented carbides. The database can be used for alloy compositions, but also their interaction with atmospheres containing oxygen, nitrogen, carbon, hydrogen, or mixtures thereof.

The database is developed and validated for simulation of the solidification process, the relative stability of matrix phases (austenite and ferrite), precipitation of secondary phases such as sulfides, borides, oxides, phosphides, carbides, nitrides, carbonitrides, and also intermetallic phases such as the sigma and laves phases.

TCFE15 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBFE9 is a corresponding mobility database that provides kinetic data for those working with the add-on kinetic modules – the Diffusion Module (DICTRA) and the Precipitation Module (TC-PRISMA) – as well as a few specific calculation types, such as Scheil with back diffusion. If you do not purchase a license for an add-on kinetic module, you most likely do not need a mobility database. One of our technical sales representatives would be happy to help you determine whether your work requires a mobility database.

MOBFE9 is compatible and recommended to be used in combination with TCFE15.

The Steel Model Library is a package of property models used to set up calculations in the Property Model Calculator that are common to those working with steels. The library currently includes nine models intended for those working in the steel industry: Martensite Temperatures, Martensite Fractions, Martensitic Steel Strength, Critical Transformation Temperatures, Pearlite, Bainite, Ferrite, CCT, and TTT Models.

The Steel Model Library is available for free to all users who have a license for the databases TCFE (version 9 or newer) and MOBFE (version 4 or newer) and a valid Maintenance & Support Subscription (M&SS).

The publications listed below are only a select few examples of how our users use the TCFE database.
