About the TCS Al-based Alloy Database (TCAL)

TCS Al-based Alloy Database (TCAL) is a thermodynamic database developed for aluminum‑based alloys, including but not limited to, the industrial grades, such as:

  • All industrial wrought aluminium alloys from 1000 series to 7000 series
  • All industrial cast aluminium alloys from 1xx.x to 8xx.x
  • Many of the 8000 and 9xx.x series, including Al-Li, Al-Sc, Al-Sn, Al-Ce, and Al-Er based alloys

In addition to thermodynamic data, it has properties data available for:

  • Molar volume with thermal expansion coefficients
  • Electrical resistivity
  • Thermal conductivity
  • Viscosity of metallic liquids
  • Surface tension of metallic liquids

TCAL10 Thermophysical Properties

The database can be used with our entire suite of products: Thermo-Calc, the Add-on Diffusion (DICTRA), Precipitation (TC-PRISMA), and/or Additive Manufacturing Modules, and all available SDKs.

The thermodynamic database is compatible with the corresponding mobility database TCS Al-alloys Mobility Database (MOBAL) that provides kinetic data for those working with the add-on kinetic modules – the Diffusion Module (DICTRA) and the Precipitation Module (TC-PRISMA) – as well as a few specific calculation types, such as Scheil with back diffusion. The current version of the mobility database is MOBAL8.

There are examples available to both demonstrate the validation of the database and to showcase the types of calculations that can be used for different materials or application areas such as process metallurgy, heat treatment, and more depending on the database. Sometimes an example is both a validation and a calculation example.

About the Database Examples

Some examples of how this database can be used include the following. Use it to:

  • Calculate various phase diagrams and property diagrams in the assessed systems as well as to extrapolate higher-order systems, and predict phase formation, phase fractions and phase compositions in multicomponent aluminum alloys.
  • Predict non-equilibrium solidification behavior of aluminum alloys. This can be at specific cooling rates when you take into account back diffusion using the Scheil calculation options in Thermo‑Calc.
  • Integrate with a compatible atomic mobility database and use it to simulate diffusion-controlled phase transformations with the add-on Diffusion Module (DICTRA) and multi-particle precipitation kinetics with the add-on Precipitation Module (TC-PRISMA).

Calculations and simulations for higher-order systems might not be valid beyond the Al‑rich region.

It is possible to combine several databases to make calculations using Thermo‑Calc. For more information related to a specific type of problem, contact one of our support specialists at info@thermocalc.com. The experts are available to make recommendations on the most suitable database to use for your needs.
