Abstract
The present invention provides a method for producing a Fe-based amorphous alloy ribbon comprising the steps of: ejecting a molten Fe-based alloy containing 10 atomic % or less of B onto a cooling roll to solidify the molten Fe-based alloy; and peeling the solidified Fe-based alloy from the cooling roll when the solidified Fe-based alloy has a temperature of 100 to 300° C. A Fe-based amorphous alloy ribbon having no crystalline phase is stably, continuously produced without breakage by this method.
Claims10
A method for producing a Fe-based amorphous alloy ribbon having a thickness of 20 μm or less, comprising the steps of:
- ejecting a molten Fe-based alloy containing 10 atomic % or less of B onto a cooling roll to solidify said molten Fe-based alloy;
- and peeling the solidified Fe-based alloy from said cooling roll when said solidified Fe-based alloy has a temperature of 150 to 280° C.
