Abstract

Influence of direct crystallizations parameters for crystalline structure, structure of high coercive station and magnetic properties permanent magnetic alloys UNDK25BA with niobium, silicon and sulfur has been investigated. It is established that UNDK25BA alloys have tendency to formation of a regular crystal structures (column or single-crystal); there is an opportunity to make such magnets on the equipment UVNS-5 intended for smelting of shovels for gas-turbine engines. The contains providing the greatest magnetic properties exceeding requirements of GOST 17809–72 and the level of foreign analogs are defined.
