Melt Viscosity of the Soft Magnetic Nanocrystalline Fe72.5Cu1Nb2Mo1.5Si14B9 Alloy

Melt Viscosity of the Soft Magnetic Nanocrystalline Fe72.5Cu1Nb2Mo1.5Si14B9 Alloy

Temperature dependences of the kinematic viscosity of a multicomponent Fe72.5Cu1Nb2Mo1.5Si14B9 melt have been studied. A critical temperature is detected above which the activation energy of the melt’ viscous flow changes. Comparison of the temperature dependences of the kinematic viscosity of the m...
