FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of tungsten-free hard alloys. Tungsten-free hard alloy is obtained by spark plasma sintering of powders obtained by electroerosion dispersion of wastes of alloy “TH20” in isopropyl alcohol, at temperature of 1,250 °C, pressure of 40 MPa and holding time of 15 minutes.
EFFECT: improved physical and mechanical properties of the alloy.
