Viscosity: Ni-Zr and Fe-Zr

The viscosity thermophysical property data is included with the TCS Zr-based Alloys Database (TCZR).

Ni-Zr

The dynamic viscosity of the Ni-Zr system has been studied extensively [1998Ohs; 2014Joh; 2017Ohi]. Except for the values reported by Ohishi et al. [2017Ohi], the other measurements are in agreement with each other. The calculated viscosity curves after assessing this system based on the experimental data are shown in the following figure.

Fe-Zr

The calculated dynamic viscosity of the Fe-Zr system along with experimental data is shown below.
