Viscosity: Al-Cu, Al-Ni, and Cu-Ni-Al

Viscosity of liquid can be calculated directly using the TCS High Entropy Alloys Database (TCHEA) as a function of chemical composition and temperature.

The viscosity thermophysical property data is included with the TCS High Entropy Alloys Database (TCHEA) as of version 4 (TCHEA4).
