Fe-based amorphous alloy ribbon having excellent soft magnetic properties, the rapidly solidified ribbon manufacturing master alloy used in the core and they were prepared using the same

摘要

It is intended to provide an alloy base for manufacturing ribbon rapidly solidified after used and their core Fe-based amorphous alloy ribbon having excellent soft magnetic properties, were produced using the present invention, cooling the substrate on a moving A metal strip that, by ejecting the molten metal through a pouring nozzle with an opening of the slot-like, obtained by rapid solidification, a non-containing P-12 at% 0.2 at% It is a Fe-based amorphous alloy ribbon is characterized in that the surface of the ribbon side, the thickness has a very thin oxide layer of 5nm or 20nm or less at least AkiraTadashihaha phase.
