TCAL1 and MOBAL2 — The Development and Validation of New Thermodynamic and Mobility Databases for Aluminium Alloys

The CALPHAD technique is a powerful tool for materials process optimization and alloy design. The quality of CALPHAD-type calculations/simulations is strongly dependent on the quality of the thermodynamic and atomic mobility databases used. In the present paper the development of a new thermodynamic database, TCAL1, and an atomic mobility database, MOBAL2, is described. Examples of thermodynamic calculations and kinetic simulations for different kinds of aluminum alloys are shown using the databases and comparing where possible against experimental data, thereby validating its accuracy.
