Viscosity of $\mathrm{Fe}$–$\mathrm{Si}$ Melts with Silicon Content up to $45$ at $\%$
Annotation
The temperature and concentration dependences of kinematic viscosity for melts of the $\mathrm{Fe}$–$\mathrm{Si}$ system with the silicon content from $3$ up to $45$ at $\%$ have been investigated. Polytherms of the viscosity of molten alloys in the heating and cooling regimes coincide (hysteresis is absent) and are satisfactorily described by the Arrhenius equation. Concentration dependences of viscosity and activation energy for viscous flow are nonmonotonic with a minimum near $5\%$ and a maximum near $25\%$ of silicon.
