MOBAL8: TCS Al-alloys Mobility Database

The TCS Al-alloys Mobility Database MOBAL8 is a kinetic database containing atomic mobility data for Al-based alloys. It 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.

MOBAL8 is compatible and recommended for use in combination with TCAL10, TCS thermodynamic database of Al-based Alloys.

With the Diffusion Module (DICTRA), MOBAL8 can be used to study several different phenomena of interest to aluminum alloys, such as e.g. microsegregation during solidification, homogenization kinetics, growth/dissolution kinetics of precipitates, and much more. In a similar way, it is also suitable for simulating concurrent nucleation, growth, and coarsening of precipitates in Al alloys by using the Precipitation Module (TC-PRISMA).

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.
