MOBNOBL2: TCS Noble Metal Alloys Mobility Database

TCS Noble Metal Alloys Mobility Database (MOBNOBL) is a kinetic database containing mobility data for noble metal alloys. It can be used for the atomic mobility descriptions of Ag-Au-Cu-Pd-Pt-based alloys for the fcc and liquid phases.

MOBNOBL2 is intended for use in combination with the TCNOBL4 TCS Noble Metal Alloys thermodynamic database.

Together with the Diffusion Module (DICTRA) and a thermodynamic database for noble metals, it can be used to study diffusion-controlled phenomena in noble metals e.g. microsegregation during solidification, homogenization kinetics, growth/dissolution kinetics of precipitates, interdiffusion, and so forth. You can also use it with the Precipitation Module (TC-PRISMA) to simulate concurrent nucleation, growth, and coarsening of precipitates in noble metal 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.
