Thermophysical Property Database

The thermophysical property database PanAl2024_TP is compatible with the PanAl2024_TH thermodynamic database and suitable for the simulation of thermophysical properties of Al-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 1150 phases assessed in the PanAl2024_TH database. It is used to calculate the density, thermal expansion, solidification shrinkage of Al alloys.

Database Validation

The simulated density changes vs. temperature of a series of Al-based alloys are shown below to validate the current PanAl2024_MV database.

Surface Tension

The surface tension of the liquid phase is added into the property database. Figure 3 shows the surface tension of a series of Al-Cu alloys in comparison with experimental data.

Viscosity

The viscosity of the liquid phase is added into the property database. Figure 4 shows the viscosity of A356 alloy in comparison with experimental data.
