Title:
Ｆｅ基アモルファス合金リボン
Document Type and Number:
Japanese Patent JP6806080
Kind Code:
B2
Abstract:
The invention provides an Fe-based amorphous alloy ribbon having a thickness of from 10 μm to 30 μm, in which a roughness curve of a central part in a ribbon width direction of the free solidified surface satisfies Rp≤3.0, Rv≤3.0, 7≤Pn≤30, 7≤Vn≤30, 0.9≤(VA/PA)<1.4, and the like, the roughness curve being measured according to JIS B 0601: 2013 by applying 20 mm in a ribbon length direction as a reference length and taking 0.8 mm as a cut-off value. Rp represents a maximum profile peak height (μm), Rv represents a maximum profile valley depth (μm), Pn represents a number of profile peaks having a height of from 0.5 μm to 3.0 μm, Vn represents a number of profile valleys having a depth of from 0.5 μm to 3.0 μm, PA represents an average of heights of five profile peaks from a highest profile peak to a fifth highest profile peak, and VA represents an average of depths of five profile valleys from a deepest profile valley to a fifth deepest profile valley.
