FIELD: metallurgy.
SUBSTANCE: method involves preparation of carbon-containing composition containing the following components, wt %: anthracite 50-85, graphite scrap 5-25, broken electrodes 5-25, graphite structure 5-15 that is crushed to the fraction of 0.1-3.2 mm, burnt at the temperature of 500-1500°C, graphite spheroids are formed in the material structure at high specific pressure of up to 20 GPa and subject to high-temperature exposure at 1800-2500°C in a reducing medium so that graphite nanostructures with the size of up to 100 nm are formed, which represent graphite nanoclusters with a hexagonal pattern.
EFFECT: production of casts of responsible purpose from high-strength cast-irons.
