FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular, to a method for producing sintered products from tungsten-free hard alloys. It can be used for the manufacture of metalworking tools. The powder material is obtained by electroerosive dispersion of waste of tungsten-free hard alloys (CST 16) in distilled water. Hot pressing is carried out in a vacuum with a high-ampere current passing through the mold and the pressed powder material at a temperature of 1200°C for 5 minutes.
EFFECT: increase in operational properties is provided.
