FIELD: metallurgy.
SUBSTANCE: alloy has two-component composite structure consisting of vanadium nitride and iron-silicon alloy. Also, weight ratio of vanadium to nitrogen in vanadium nitride is within ranges from 3.7:1 to 6.0:1, while weight ratio of iron to silicon in iron-silicon alloy is within ranges from 120:1 to 3:1. Alloy has density from 4.2 to 6.9 g/cm3, general porosity from 1.0-28.0%, compression strength from 2 to 192 MPa at the following ratio of components in it, wt %: vanadium nitride 40-90, iron silicon alloy - the rest.
EFFECT: universal nitrogen containing alloy facilitating melting all grades of steel at minimal consumption of alloy proper with maximal high degree of nitrogen and vanadium absorption with liquid metal.
