About the TCS Mg-based Alloys Database (TCMG)

TCS Mg-based Alloys Database (TCMG) is a thermodynamic and properties database for magnesium-based alloys. It can be used for a wide range of compositions from pure magnesium to very complex magnesium-based commercial magnesium alloys. It can be used for calculating phase diagrams and thermodynamic properties of assessed systems, but also for predicting phase equilibria and simulating solidification processes for a wide range of magnesium alloys of industrial relevance, including:

  • Mg-Al based alloys such as AZ, AE, AJ, AM, AS, and AX
  • Mg-Zn-Zr alloys such as ZK60
  • Mg-RE (rare earth)-Zn (EZ) alloys
  • Mg-RE-Zr alloys such as WE
  • Experimental magnesium alloys under development

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

  • Electrical resistivity of all solid phases and liquid
  • Thermal conductivity of all solid phases and liquid
  • Molar volume and thermal expansivity of all solid phases and liquid
  • Viscosity of liquid
  • Surface tension of liquid

TCMG8 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 Mg-alloys Mobility Database (MOBMG) 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 is MOBMG2.

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

The TCS Mg-based Alloys Database (TCMG) enables predictions (such as multi-component phase equilibria calculations, equilibrium solidification simulation and Scheil solidification simulation) to be made for multicomponent systems and alloys of industrial importance. This means that the database can be utilized to extrapolate to higher-order systems by combining several critically assessed systems.

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.
