Magnesium-based Alloys Databases

TCMG9 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.

TCMG9 for Thermodynamic and Properties Data

TCMG9 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

TCMG9 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 TCMG9.

Highlights of the Latest Release

The new version of our Magnesium-based Alloys Database, TCMG9, was released with Thermo-Calc 2026b. For this release, one of the primary focuses was on revising the Gd–Mg system to align with newly determined experimental phase boundaries and the metastable phases that emerge during aging, thereby enabling age-hardening simulations using the Precipitation Module (TC-PRISMA). Furthermore, several ternary systems, including Ca–Mg–Zn, Ce–Mg–Zn, and Nd–Mg–Zn, were critically reassessed. Read the Release Notes for more details.

  • 27 new phases (602 total)
  • 3 new binary systems assessed (232 total)
  • 14 new ternary systems assessed (147 total)
  • Several binary and ternary systems reassessed
  • Adds elastic properties for BCC (A2 and B2), FCC (A1 and L12), and HCP (A3 and DHCP) phases
    • The elastic constants description can be used to derive the elastic moduli (bulk modulus, shear modulus, and Young’s modulus) for a single-phase microstructure
    • Molar volumes, surface tensions, viscosities and resistivities/conductivities are updated with the additions of new phases
    • The addition of elastic properties enables the calculation of elastic constants and moduli in magnesium-based alloys

1: Elastic properties are only available for cubic BCC (A2 and B2), cubic FCC (A1 and L12), and hexagonal HCP (A3 and DHCP) phases.
