METHOD OF THERMOMAGNETIC TREATMENT OF MAGNETICALLY SOFT MATERIALS Russian patent published in 1994 - IPC

Abstract RU 2025504 C1

FIELD: metallurgy. SUBSTANCE: method includes high temperature annealing in non-oxidizing medium (vacuum), holding, cooling, thermomagnetic treatment in sign-variable magnetic field of 0.1 - 10 kHz frequency during 1 to 3 min at 400 - 500 C followed by cooling (in the field) at room temperature. EFFECT: improved properties of magnetically soft materials. 3 cl, 3 tbl
