PLATE FROM IRON OR IRON ALLOY, AND ITS MANUFACTURING METHOD Russian patent published in 2014 - IPC C22C38/00 C21D8/12 C23C2/04 C23C10/28 H01F1/16 

FIELD: metallurgy.

SUBSTANCE: method involves creation of metallic layer (2) with a ferrite-forming element at least on one surface of plate (1) made from Fe or Fe alloy with α-γ conversion. Then, plate (1) and metallic layer (2) is heated up to temperature A3 Fe or Fe alloy. Ferrite-forming element diffuses into plate (1) from parent metal so that area (1b) of alloy with ferrite phase is created. In ferrite phase there obtained is accumulation degree of planes {200} 25% or more, and accumulation degree of planes - {222} 40% or less. Then, plate (1) is additionally heated up to the temperature exceeding temperature A3 Fe or Fe alloy. With that, accumulation degree of planes {200} increases, and accumulation degree of planes {222} decreases at simultaneous preservation in area (1b) of alloy of ferrite phase.

EFFECT: providing high density of a magnetic flux in a plate.
