PROCESS FOR THE HEAT TREATMENT, IN A MAGNETIC FIELD, OF A COMPONENT MADE OF A SOFT MAGNETIC MATERIAL

摘要

A magnetisable material such as an iron-nickel-molybdenum 15-80-5 alloy, an amorphous cobalt-based alloy or an iron-silicon-copper-niobium-boron nanocrystalline alloy is heated below the Curie point. It is subjected to a magnetic field whose intensity is varied over time, following a series of peaks. The intensity is progressively increased to a maximum and thereafter decreased to a minimum. The field may be longitudinal, transverse, unidirectional, continuous or alternating.
