METHOD FOR OBTAINING FERRITE ITEMS Russian patent published in 2015 - IPC B22F3/12 H01F1/10 H01F1/34 

FIELD: metallurgy.

SUBSTANCE: invention refers to powder metallurgy. A method for obtaining ferrite items involves preparation of moulding powder containing ferrite material and an alloying additive, pressing of workpieces, radiation thermal sintering of workpieces by their heating to temperature of sintering by irradiation with a penetrating electron beam with exposure at the temperature under irradiation with a continuous electron beam. As an alloying additive to the moulding powder there added is nanosized powder of carbonyl iron with particle size of 320-450 nm in the amount of 0.01-0.03 wt % of total weight of the moulding powder.

EFFECT: improvement of a sintering process, reduction of sintering time and improvement of quality of ferrite items.
