Thermophysical Properties Examples

This is an example of including viscosity in the calculations.

Using the FEDEMO database, which is the free demonstration version of the TCS Steel and Fe-alloys Database (TCFE), the viscosity of metallic liquids is plotted at 1873 K for Cu-Ni and compared to experimental data from [2005Sat].

The example includes an experimental data (*.exp) file called Cr-Ni_1873K.exp.

The same example is also provided in Graphical Mode as T_12_Viscosity_in_Cr-Ni.tcu.

This is an example of including surface tension in the calculations.

Using the ALDEMO database, which is the free demonstration version of the TCS Al-based Alloy Database (TCAL), the surface tension of liquid metallic is plotted at 1373 K for Cu-Zr and compared to experimental data from [2005Kra].

The example includes an experimental data (*.exp) file called Cr-Zr_ALDEMO.exp.

The same example is also provided in Graphical Mode as T_11_Surface_tension_in_Cu-Zr.tcu.

There are two examples that include molar volume in the calculations and use the ALDEMO database, which is the free demonstration version of the TCS Al-based Alloy Database (TCAL).

The examples calculate volumetric thermal expansion coefficients of the L12-type Al3Sc (tcex58) and the L12-type Al3Zr (tcex59), respectively. Both Al3Zr and Al3Sc are modeled as the same phase (named as AL3SC, since Al3Sc is stable while Al3Zr is metastable).

The examples include an experimental data (.exp) file called Al3X.exp, which is the same for both examples to read the data from [2015Sah].

The same example, combining both tcex58 and tcex59 is also provided in Graphical Mode as T_15_Molar_Volume_for_Al3Sc-Al3Zr.tcu.

This example calculates the electrical resistivity (ELRS) and thermal conductivity (THCD) or pure Cu. It makes a step calculation over a wide temperature range, covering both the FCC_A1 state and the liquid state. It plots thermal conductivity of the system (both FCC_A1 and liquid) and that of a single phase (taking FCC_A1 as an example), respectively. Also plots electrical resistivity of the system and that of FCC_A1.

The example is available to all users as it uses the ALDEMO database, which is the free demonstration version of the TCS Al-based Alloy Database (TCAL).

The example includes two experimental data (*.exp) files called 1972Ho_cu_thcd.exp and 1981Ho_cu_elrs.exp.

The same example is also provided in Graphical Mode as T_16_Electrical_Resistivity_Thermal_Conductivity_Cu.tcu

The thermophysical properties are progressively being added to the Thermo‑Calc databases starting with Thermo‑Calc software version 2020a.

You can learn more about the models by searching the help (press F1 when in Thermo‑Calc).

You can find information on our website about the properties that can be calculated with Thermo‑Calc and the Add‑on Modules.
