摘要：
It is established that the formation of a viscous film on the surface of a melt is possible during the viscosimetry of Fe–B melts under normal conditions. It is noted that the film has a considerable effect on the results from measurements and can lead to the appearance of additional features on polyterms. Thermodynamic analysis of the composition of surface layers shows that a viscous film contains mainly boron oxide B2O3. It is concluded that the evaporation of B2O3 from the surface of the alloy produces additional anomalies on the polytherm of viscosity.
