Thermophysical Property Database

The thermophysical property database PanNoble2026_TP is compatible with the PanNoble2026_TH thermodynamic database and suitable for the simulation of thermophysical properties of noble metal 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 phases assessed in the PanNoble_TH database. It is used to calculate the density, thermal expansion, solidification shrinkage of the alloys.

The simulated density changes vs. temperature of a series of noble metal alloys are shown below to validate the current PanNoble_MV database.

Surface Tension

The surface tension of the liquid phase is added into the property database. Figure 3.3 shows the surface tension of a series of Cu-Ni alloys in comparison with experimental data.

Viscosity

The viscosity of the liquid phase is added into the property database. Figure 3.4 shows the viscosity of Cu-Mg alloys in comparison with experimental data.
