Zusammenfassung:	PCT No. PCT/SU80/00217 Sec. 371 Date Sep. 21, 1981 Sec. 102(e) Date Sep. 21, 1981 PCT Filed Dec. 25, 1980 PCT Pub. No. WO81/02168 PCT Pub. Date Aug. 6, 1981.The metal composition and the process for producing same relate to the art of alloy metallurgy. The metal composition based on metals of VIII Group and nitrides of metals of III-VII Groups is characterized in that at least one alloy containing at least one metal of VIII Group and at least one metal of III-VII Groups are disintegrated to powder, placed into a nitrogen-containing atmosphere with an excess of nitrogen, burning is initiated by way of a local ignition of the mixture at any point thereof and the excess of nitrogen is maintained till completion of the reaction. The metal composition and process for producing same according to the present invention are useful in the manufacture of hard alloys based on refractory or high-melting compounds.
