Abstract

Fe-Si-B systems amorphous alloys were rapidly solidified from the melt by the single roller method. In this process the alloys were melted in a crucible and the molten alloy is jetted through a small orifice by gas pressure or gravity. The effects of the jetting temperature of the melting alloy on the ribbon thickness of rapidly solidified Fe75Si10B15 and Fe79.5Si8.5B12 alloys were examined. The rapidly solidified Fe75Si10B15 and Fe79.5Si8.5B12 alloy ribbons’ mean thickness decreased continuously with the increased jetting temperature. However, the temperature dependence of the ribbon thickness in the Fe79.5Si8.5B12 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, the ribbon thickness decreases.
