FIELD: metallurgy. ^ SUBSTANCE: invention refers to iron and steel and non-ferrous metallurgy, particularly to production of nitrated ferroalloys and addition alloys for following alloying of steel, copper and aluminium with nitrogen. As basic initial materials metals of I, II groups and their alloys, nonmetals of III-VIII groups of periodic table are used, and as an additive nitride generating metals and/or their alloys are used. Only an additive is subject to nitriding under a burning mode. Crushed basic initial materials and the product of additive nitriding are mixed at a mass ratio (1-5):1, then the mixture is compacted, and sintered or melted. The invention extends assortment of nitrided materials; with ferroalloys and addition alloys acquiring new characteristics; it also allows regulation of nitrogen contents, density values and melting temperatures of ferroalloys and addition alloys, including on those base of materials where nitriding by means of known methods is impossible. ^ EFFECT: extension of assortment of nitrided materials with ferroalloys and addition alloys acquiring new characteristics; possibility to regulate nitrogen contents and values of density and melting temperature of ferroalloys and addition alloys. ^ 2 cl, 2 ex, 1 tbl |
