More about PanMg Database

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 31 components, 814 phases, and 373 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 814 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.

Applications

Calculated liquidus projection of the Mg-Al-Sr ternary system superimposed with Scheil simulated solidification paths of three Mg-Al-Sr alloys

The calculated liquidus projection of the Mg-Al-Sr ternary system. The solidification paths of three selected Mg-Al-Sr alloys using the Scheil model shown in this figure can be used to predict the casting microstructures of these alloys.
