Magnesium-based Alloys Databases

TCMG8 is our thermodynamic and properties database designed for use with magnesium-based alloys. It can be used for a wide range of compositions from pure Mg to very complex Mg-based commercial magnesium alloys. MOBMG2 is the corresponding mobility database needed for use with the add-on kinetic modules.

TCMG8 for Thermodynamic and Properties Data

TCMG8 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

TCMG8 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBMG2 for Kinetic Data

MOBMG2 is a corresponding mobility database 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. If you do not purchase a license for an add-on kinetic module, you most likely do not need a mobility database. One of our technical sales representatives can help you determine whether your work requires a mobility database.

MOBMG2 is compatible and recommended to be used in combination with TCMG8.
