Viscosity of Fe90B x Si(10 − x) melts

High Temperature - The temperature dependences of the viscosity of liquid Fe90B x Si(10 − x) alloys are studied in the mode of heating and subsequent cooling. The temperature dependences of...     

Viscosity of Fe-Si melts with silicon content up to 45 at %

The temperature and concentration dependences of kinematic viscosity for melts of the Fe-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.
