MOBFE8: TCS Steels/Fe-Alloys Mobility Database

The TCS Steels/Fe-Alloys Mobility Database (MOBFE) is a kinetic database containing mobility data limited to Fe-based alloys. Data is present in a format suitable for simulation of diffusion controlled phenomena using the add-on Diffusion Module (DICTRA) and/or Precipitation Module (TC-PRISMA), and/or for use together with any Thermo‑Calc programming interface.

MOBFE8 is compatible and recommended for use in combination with the TCFE14 (TCS Steels/Fe-Alloys Database) thermodynamic database.

Primarily for aiding alloy design and the optimization of manufacturing processes, through simulation of different diffusion controlled phenomena, such as e.g. microsegregation during solidification, homogenization, kinetics of phase transformations, precipitate growth/dissolution kinetics, carburization, nitriding, and much more.

The CALPHAD Method

The Thermo‑Calc databases are developed with the CALPHAD approach based on various types of experimental data and theoretical values (e.g. those from first-principles calculations). It is based on the critical evaluation of binary, ternary, and for some databases, important higher order systems. This enables predictions to be made for multicomponent systems and alloys of industrial importance. Among these, the thermodynamic database is of fundamental importance.
