Document Type and Number:
Japanese Patent JP4402960
Kind Code:
B2
Abstract:
The present invention provides an iron-base amorphous alloy thin strip excellent in soft magnetic properties, an iron core manufactured by using said thin strip, and a mother alloy for producing a rapidly cooled and solidified thin strip. More specifically, the present invention is an iron-base amorphous alloy thin strip produced by rapidly cooling and solidifying molten metal by ejecting it onto a moving cooling substrate through a pouring nozzle having a slot-shaped opening, characterized by having an ultra-thin oxide layer of a thickness in the range from 5 to 20 nm on one or both of the surfaces of the amorphous mother phase containing P in the range from 0.2 to 12 atomic %.
