Viscosity: B-Fe, Fe-Ni, and Fe-Ni-B
The TCS Steel and Fe-alloys Database (TCFE)can be used to calculate the viscosity of the metallic liquid. Below are a few examples of the calculated viscosity curves compared with the experimental data. The viscosity thermophysical property data is included with the database as of version 10 (TCFE10).
B-Fe and Fe-Ni
The calculated viscosity of the B-Fe and Fe-Ni binary systems are compared with the experimental data.

Figure 1: Dynamic viscosity of B-Fe at 1773 K (left) and Fe-Ni at 1873 K (right). Experimental data are from [1999Tom; 2005Lad; 2005Sat; 2015Tak].
Fe-Ni-B
The following shows the dynamic viscosity of two liquid B-Fe-Ni alloys as a function of temperature along with the experimental data from [2004Yam]. They have used oscillating crucible method for measuring the viscosity of these alloys from melting point to about 1673 K under a purified helium atmosphere.
Figure 2: Calculated dynamic viscosity of Fe-Ni-B ternary alloys as a function of temperature. Melting temperature of the alloys are marked on the plot. The experimental data are taken from [2004Yam].
