Production and properties of soft-magnetic dielectric materials based on nanocrystalline Fe73Si15B7.2Cu1Nb3 alloy powder

Powder metallurgy methods are used to produce soft magnetic compact materials from amorphous and nanocrystalline alloys. Toroid-shaped samples are warm-pressed from nanocrystalline Fe 73 Si 15 B 7.2 Cu 1 Nb 3 alloy powders and SFP-012A resin binder. The method does not require additional thermal tre...

More Information
Summary:Powder metallurgy methods are used to produce soft magnetic compact materials from amorphous and nanocrystalline alloys. Toroid-shaped samples are warm-pressed from nanocrystalline Fe 73 Si 15 B 7.2 Cu 1 Nb 3 alloy powders and SFP-012A resin binder. The method does not require additional thermal treatment and the samples are ready to use. The key influence on the properties of soft magnetic powder materials is produced by ferromagnetic filling factor (FFF). The optimal experimental conditions to make samples with the minimum porosity and maximum FFF are determined. The density of the samples depending on compaction parameters and resin content is established.
