PanMagnesium

PanMagnesium Quick Overview

PanMagnesium – Thermodynamic database (TH), Mobility database (MB), and Thermophysical property (TP) database for multi-component magnesium alloys.

• The current PanMg_TH thermodynamic database consists of 31 components, 854 phases, and 384 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 PanMg_TP thermophysical property database includes the molar volume database covers all the phases assessed in the PanMg_TH, the surface tension and viscosity properties for the liquid phase, and the thermal conductivity. It can be combined with the thermodynamic database for the simulation of thermo-physical properties of Mg-based alloys, such as density, thermal expansion, and solidification shrinkage.  Thermal conductivity database can be used to calculate the thermal conductivity of the alloys under equilibrium, as-cast and as quenched three different conditions.

Applications

Coupling PanMg_TH thermodynamic database with PanMg_MV molar volume database, user can calculate  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.
