摘要： A method for producing an ultrafine-crystalline alloy ribbon having a structure in which crystal grains having an average grain size of 1-30 nm are dispersed at a ratio of 5-30% by volume in an amorphous matrix ultrafine, comprising the steps of ejecting an alloy melt onto a rotating cooling roll to quench it; forming an easily windable ribbon having such toughness that it is not fractured when bent to a bending radius of 1 mm or less, before the start of winding around a reel; and changing the forming conditions of the ribbon after the start of winding around a reel, to obtain a structure in which ultrafine crystal grains having an average grain size of 1-30 nm are dispersed at a ratio of 5-30% by volume in an amorphous matrix.
