Thermophysical Property Database

The thermophysical property database PanNi2026_TP is compatible with the PanNi_TH thermodynamic database and suitable for the simulation of thermophysical properties of Ni-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 343 phases assessed in the PanNi_TH database. It is used to calculate the density, thermal expansion, solidification shrinkage of Al alloys.

The simulated density changes vs. temperature of a series of Ni-based alloys are shown below to validate the current PanNi2026_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 Al-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 Ni-Cr alloy in comparison with experimental data.
