Thermophysical Property Database
The thermophysical property database PanRHEA2024_TP is compatible with the PanRHEA2024_TH thermodynamic database and suitable for the simulation of thermophysical properties of refractory high entropy alloys(RHEA). 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 509 phases assessed in the PanRHEA2024_TH database. It is used to calculate the density, thermal expansion, solidification shrinkage of the alloys.
Figure 1 shows the calculated molar volume of Bcc Mo-Ti and Nb-Ti binary alloys at room temperature with experimental data from Ref. [2016Yan]. One can see that the calculated results using the current PanREHA_MV database can well describe the experimental measurements.

Surface Tension
The surface tension of the liquid phase is added into the property database. Figure 2 shows the surface tension of the HfNbTaTiZr refractory high entropy alloy.
Viscosity
The viscosity of the liquid phase is added into the property database. Figure 3 shows the viscosity of the HfNbTaTiZr refractory high entropy alloy.
