FIELD: powder metallurgy.
SUBSTANCE: invention relates to production of iron alloys from iron-containing wastes. Proposed method consists of preparation of mixture of powders and self propagating high-temperature synthesis. 20-25 mass % of aluminum powder is mixed with 75-80 mass % if iron scale to get thermit mix. In process of mixing, titanium carbide, 10-14 % of thermit mix mass, titanium boride, 3-5% of thermit mix mass and chromium, 4-5% of thermit mix mass are added into thermit mix.
EFFECT: production of alloy of preset content featuring high hardness, reduced time taken for process.
