The Effect of the Jetting Temperature on the Fabrications of Rapidly Solidified Fe-Si-B Systems Alloys Using Single Roller Melt Spinning

Abstract

  The effects of the jetting temperature of the melting alloy on the ribbon thickness of rapidly solidified Fe₇₅Si₁₀B₁₅ and Fe_79.5Si_8.5B₁₂ alloys were examined. The rapidly solidified Fe₇₅Si₁₀B₁₅ and Fe_79.5Si_8.5B₁₂ alloy ribbons' mean thickness decreased continuously with the increased jetting temperature. However, the temperature dependence of the ribbon thickness in the Fe_79.5Si_8.5B₁₂ alloy was greater than that of the Fe₇₅Si₁₀B₁₅ alloy.
   The results demonstrate that the viscosity of liquid Fe-Si-B systems alloys influences the ribbon thickness. Moreover, when the contact conditions between the rotating roll comes and puddle are good, then the ribbon thickness decreases.
