By using Thermo-Calc and compatible thermodynamic databases, a vast amount of information can be obtained of relevance for multicomponent Al-based alloys.
Examples of properties that can be predicted:
During casting, welding and joining of Al alloys, the solidification of the alloys happens almost entirely in a non-equilibrium way. The non-equilibrium solidification path can be predicted rather accurately by using the Scheil-Gulliver module available in Thermo-Calc.
From a multicomponent Scheil-Gulliver calculation, one can obtain:
By using the Diffusion Module (DICTRA) and combining both thermodynamic and kinetic databases, typical diffusion-controlled phase transformations in Al-alloys can be simulated under arbitrary heat treatment conditions.
Examples of applications that can be studied using the Diffusion Module (DICTRA) include:
By using the Precipitation Module (TC-PRISMA) and combining thermodynamic and kinetic databases, the concurrent nucleation, growth and coarsening of precipitates can be simulated.
Precipitation Module (TC-PRISMA) simulation results include the temporal evolution of:
The CALPHAD method has recently been extended to model additional thermophysical properties. The most recent version of the TCS Aluminium-based Alloys Database has electric resistivity, thermal conductivity, surface tension of liquid, viscosity of liquid and molar volume included.
