Thermophysical Property Database

The thermophysical property database PanMo2024_TPis compatible with the PanMo2024_TH thermodynamic database and suitable for the simulation of thermophysical properties of Mo-based alloys. It includes the molar volume data for all the phases, surface tension and viscosity properties for the liquid phase.

Molar Volume

The current molar volume database covers all 208 phases assessed in the PanMo2024_TH database. It is used to calculate the density, thermal expansion, solidification shrinkage of Mo alloys.

The simulated density changes vs. temperature of a series of Mo-based alloys are shown below to validate the current PanMo2024_MV database.
