Abstract

Powder metallurgy is a method to produce compact soft magnetic materials based on amorphous and nanocrystalline alloys. The toroid-shaped samples are warm-pressed from Fe73Si15B7,2Cu1Nb3 nanocrystalline alloy powders and SFP-012A resin as a binding agent. This method does not require additional thermal treatment and the samples are ready for use. The main factor that influences the magnetic properties of soft magnetic powder materials is ferromagnetic filling factor (FFF). The optimal experimental conditions to make samples with minimal porosity and maximal FFF are determined. The density of the samples is established depending on compaction parameters and resin content.
