METHOD FOR PREPARING MAGNETIC-SOFT PRODUCTS OF HIGH DENSITY Russian patent published in 2007 - IPC B22F3/87 H01F1/22 

FIELD: powdery metallurgy.

SUBSTANCE: invention relates to methods for preparing high-density molding materials from magnetic-soft components. Method for preparing high-density molding materials for magnetic-soft semifinished products used in alternate magnetic fields involves the high-rapid pressing magnetic-soft iron powder or magnetic-soft iron-base powder in a monoaxial moving pressing plunger at the rate at least 2 m/s. Method provides enhancing the parent magnetic permeability and frequency stability with a similar density.

EFFECT: improved preparing method.
