PanMagnesium – Thermodynamic database (TH), Mobility database (MB), and Molar volume (MV) database for multi-component magnesium alloys.

  • The current PanMg_TH thermodynamic database consists of 27 components, 574 phases, and 211 fully assessed binary, ternary and quaternary systems. It can be used to describe thermodynamic properties and phase equilibrium of casting and wrought magnesium-rich alloys.
  • The current PanMg_MB mobility database includes assessed mobility model parameters for the Liquid, Bcc, Fcc, and Hcp solution phases. It is compatible with PanMg_TH and suitable for the simulation of diffusion controlled phenomena of multi-component magnesium alloys.
  • The current PanMg_MV molar volume database covers all the 574 phases assessed in PanMg_TH, and can be combined with the thermodynamic database for the simulation of thermo-physical properties of magnesium alloys, such as density and thermal expansion.

Coupling PanMg_TH thermodynamic database with PanMg_MV molar volume database, user can calculateĀ  molar volume, density, thermal expansion, and other properties. This is an example which compares the calculated and measured molar volume of Mg-Li alloys in Fcc, Bcc, and Hcp phases.
