Abstract
The present disclosure provides a method that ensures easily manufacturing an alloy ribbon piece having excellent soft magnetic properties. The method is a method for manufacturing an alloy ribbon piece obtained by crystallizing an amorphous alloy ribbon piece and including: increasing a temperature of the amorphous alloy ribbon piece to a crystallization starting temperature; and increasing the temperature of the amorphous alloy ribbon piece from the crystallization starting temperature to a crystallization process termination temperature equal to or less than a crystallization completion temperature. A temperature increase rate of the amorphous alloy ribbon piece in the increasing of the temperature of the amorphous alloy ribbon piece from the crystallization starting temperature to the crystallization process termination temperature satisfies ΔQ≤ΔQ+mcΔT where a self-heating amount, a heat discharge amount, a mass, a specific heat, and a temperature increase width of the amorphous alloy ribbon piece per unit time is ΔQ, ΔQ, m, c, and ΔT, respectively.
