MOBTI5: TCS Ti-alloys Mobility Database

The TCS Ti-alloys Mobility Database (MOBTI) is a kinetic database containing atomic mobility data limited to Ti/TiAl-based alloys.

MOBTI5 is compatible and recommended for use in combination with the TCTI6 TCS Ti/TiAl-based Alloys thermodynamic database.

When the database is used with the Add-on Diffusion Module (DICTRA), you can study several diffusion-controlled phenomena in Ti/TiAl based alloys, such as microsegregation during solidification, homogenization kinetics, growth/dissolution kinetics of precipitates, and much more.

Similarly when combined with the Add-on Precipitation Module (TC-PRISMA), is suitable to simulate concurrent nucleation, growth, and coarsening of precipitates in Ti/TiAl-alloys.

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.
