METHOD OF THERMAL TREATMENT OF MAGNETIC COMPONENT MADE FROM MAGNETIC MATERIAL IN MAGNETIC Russian patent published in 2002 - IPC

FIELD: methods of thermal treatment of magnetic components in magnetic field. SUBSTANCE: proposed method consists in thermal treatment of magnetic component, for example magnetic core or differential switch made from soft magnetic material at low anisotropy, such as FeNiMo 15-80-5 alloy, Co-based amorphous alloy or Fe- SiCuNbB nanocrystal alloy. Method includes also annealing at temperature below Curie point at simultaneous action of longitudinal or transversal unidirectional permanent or variable magnetic field applied in form of successive strobe pulse. Each such pulse has first part when intensity of magnetic filed reaches its maximum and second part when magnetic field intensity is minimum. EFFECT: possibility of obtaining magnetic component from material characterized by hysteresis loop at Br/Bm ratio from 0.3 to 0.9. 10 cl, 1 dwg, 1 tbl
