FE-BASE AMORPHOUS ALLOY THIN STRIP OF EXCELLENT SOFT MAGNETIC CHARACTERISTIC, IRON CORE PRODUCED THEREFROM AND MASTER ALLOY FOR QUENCH SOLIDIFICATION THIN STRIP PRODUCTION FOR USE THEREIN

摘要

The present invention relates to a rapidly solidified thin ribbon for making master alloys used in the iron cores and those prepared by, using this thin ribbon, soft magnetic properties are excellent Fe-based amorphous alloy, on cooling the substrate to move, having an opening of the slot-like as the metal thin ribbon obtained by ejecting and rapidly solidified molten metal through the pouring nozzle, to at least a thin ribbon surface of one of the amorphous matrix containing P of less than 12 at% at least 0.2 atomic% and having an oxide layer the ultra-thin having a thickness of at least 5nm 20nm It relates to a Fe-based amorphous alloy thin ribbon of the features. ; Amorphous alloy thin, rapidly solidified, Mo alloy, ultra-thin oxide layer, the segregation phase, transformers, iron core, soft magnetic properties, core loss, magnetic flux density, annealing
