Abstract
Official abstract text for this publication.
A method for manufacturing an alloy ribbon piece containing a nanocrystalline alloy includes: preparing an alloy ribbon containing an FeNiB-based amorphous alloy; heating a processing planned portion at a circumference of a crystallization planned portion that is an area in which the alloy ribbon piece is punched of the alloy ribbon to a first temperature range in which crystal grains of αFe and crystal grains of Fe2B deposit to cause the crystal grains of αFe and the crystal grains of Fe2B to deposit, and simultaneously heating the crystallization planned portion to a second temperature range of a crystallization starting temperature or higher and lower than the first temperature range to crystallize the crystallization planned portion; and punching an area including the crystallization planned portion from the alloy ribbon by shearing the processing planned portion of the alloy ribbon after the thermal processing step to form the alloy ribbon piece.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing an alloy ribbon piece containing a nanocrystalline alloy, comprising: preparing an alloy ribbon containing an FeNiB-based amorphous alloy; heating a processing planned portion at a circumference of a crystallization planned portion that is an area in which the alloy ribbon piece is punched of the alloy ribbon to a first temperature range in which crystal grains of αFe and crystal grains of Fe 2 B deposit to cause the crystal grains of αFe and the crystal grains of Fe 2 B to deposit, and simultaneously heating the crystallization planned portion to a second temperature range of a crystallization starting temperature or higher and lower than the first temperature range to crystallize the crystallization planned portion; and punching an area including the crystallization planned portion from the alloy ribbon by shearing the processing planned portion of the alloy ribbon after the heating to form the alloy ribbon piece. 2 . The method for manufacturing an alloy ribbon piece according to claim 1 , wherein in the heating, the first temperature range is 600° C. or higher and 650° C. or lower, and the second temperature range is 470° C. or higher and 500° C. or lower.
