ADVANCES IN SOFT MAGNETIC ALLOYS

Abstract

This present work pretend to give a general vision of last three years advance of softmagnetic materials. Centralised in Fe rich alloys of nanocrystalline, and in some cases amorphous. Were classified three big group of alloys, first agreed to heat treatment and heating rates, second consider adition of component in the softmagnetic alloy structure and third agreed to amorphous matrix composition and grain size.

These study revealed Glass forming ability GFA is a key propierty to obtain amorphous alloys, represent a bottleneck in a amorphuos and nanocrystalline alloys manufacturing process. Besides, heat treatment process like Joule Heating open new posibility for obtain softmagnetic nanocrystalline alloys. Being a good option Nanomet alloys, posing new annealing configuration to this.
