By using Thermo-Calc and compatible thermodynamic databases, a vast amount of information can be obtained of relevance for Si-based alloys.
Examples of equilibrium properties that can be predicted:
The solidification of Si-based alloys during casting happens in a non-equilibrium way. The non-equilibrium solidification path can be predicted rather accurately by using Scheil-Gulliver available in Thermo-Calc.
From a multicomponent Scheil-Gulliver calculation, one can obtain:
By using the Diffusion Module (DICTRA) and combining corresponding thermodynamic and kinetic databases, typical diffusion-controlled phase transformations in Si-based 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:
