PROCESS FOR MANUFACTURING A MAGNETIC CORE MADE OF A NANOCRYSTALLINE SOFT MAGNETIC MATERIAL

摘要

: Process for manufacturing at least one magnetic core made of an iron-based soft magnetic alloy having a nanocrystailing structure, characterized in that an amorphous ribbc u is manufactured from the magnetic alloy, the annealing emperature Tm which, in the case of the ribbon, leads to maximum magnetic permeability, is determined, at least one core blank is manufactured from the ribbon and it least one core blank is subjected to at least one annealing operation, the said annealing being carried out at a temperature T of between Tm + 10°C and Tm + 50°C for a temperature hold time t of between 0.1 and 10 hours so as to cause nanocrystals to form.
