摘要： A nanocrystalline alloy wherein at least 50 volume % of an alloy structure consists of a crystal grain mainly comprising bcc-phase having a grain size of 50 nm or less, a saturation magnetic flux density of the alloy is 1 T or more, a remanent flux density of the alloy is 0.4 T or less, and an Fe--B compound phase is partially formed in the alloy. The nanocrystalline alloy produced by heat treatment without applying any magnetic field shows pulse attenuation characteristics comparable to or more excellent than those of a nanocrystalline alloy obtained by heat treatment in a magnetic field.

摘要： An amorphous alloy ribbon free from embrittlement and crystallization and having excellent surface conditions and shape in edge portions is produced by (a) preparing an alloy melt having a composition comprising 13 atomic % or less of B and 15 atomic % or less of at least one selected from the group consisting of transition elements of Groups 4A, 5A and 6A, the balance being substantially Fe; (b) ejecting the alloy melt at a temperature from the melting point of the alloy +50° C. to the melting point of the alloy +250° C. through a nozzle onto the cooling roll rotating at a peripheral speed of 35 m/second or less, a distance between a tip end of the nozzle and the cooling roll being 200 &mgr;m or less; (c) starting to supply a gas based on CO2 to the alloy melt after the surface temperature of the cooling roll has become substantially constant; and (d) grinding the cooling roll while supplying the gas based on CO2.

摘要： 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.
