FIELD: production of alloys based on rare-earth metals. SUBSTANCE: alloys are produced by method of metallothermal reduction of their halogenides in atmosphere of inert gas with intensive mixing in presence of alloying components. Separate smelting of metal-reductant and mixture of alloying component, reduced compound and fluxes, reducing reaction in liquid phase are conducted, alloy is cured in molten condition with electromagnetic mixing for 0.5-20.0 min, cristallized and cooled in melting pot transparent for electromagnetic field in induction furnace. EFFECT: enhanced efficiency of process.
