TCZR1 Thermophysical Properties

The following properties data is included with the TCS Zr-based Alloys Database (TCZR).

• In total, 28 binary systems have viscosity parameters for the liquid phase.
• 28 binary systems have surface tension parameters for the liquid phase.
• Volume parameters have either been assessed or estimated for all solid phases and for the liquid phase. Interactions have been either assessed or estimated for every binary combination in the common solution phases, including liquid, FCC_A1, BCC_A2 and HCP_A3.

Parameters and Variables

Below is a summary of the available thermophysical parameters and variables for the databases when working in Thermo‑Calc. There are differences when you are working in Console Mode versus Graphical Mode as well as if you use an SDK such as TC‑Python or TC-Toolbox for MATLAB®.

Property	Model Parameters	Variables to Show or Plot in Console Mode and TC‑Python
Surface tension	SIGM, XI	SURF(LIQUID)
Dynamic viscosity	VISC	DVIS(LIQUID)
Kinematic viscosity		KVIS(LIQUID)
Molar volume	V0, VA	VM for a system VM(PHI) for phase PHI
