METHOD TO PRODUCE MODIFIED ADDITION ALLOYS NEODYMIUM-IRON FOR CONSTANT MAGNETS NEODYMIUM-IRON-BORIUM Russian patent published in 2017 - IPC C21C7/00 B82Y30/00 C22C1/02 

Abstract RU 2626841 C2

FIELD: metallurgy.

SUBSTANCE: modifier in the form of nanodispersed mechanically activated neodymium oxide powder, iron clad, with the particle size 50-100 nm, in the amount of 0.03-0.07 wt % of the stock mass, is introduced into the stock melting in the furnace, provide the holding of the resulted addition alloy melt, after which the melt is poured into the mould, the heating temperature of which is 100-200°C.

EFFECT: invention makes it possible to produce the permanent magnets with higher magnetic properties due to producing the addition alloy with the fine crystalline granular structure.
