FIELD: metallurgy.
SUBSTANCE: work pieces from the powdered high-speed steel obtained by electroerosive dispergating of wastes of high-speed steel of P6M5 grade in the distilled water are obtained by hot pressing of powder with passing of high-ampere current in vacuum within 2.9…3.1 minutes at the temperature 895…905°C.
EFFECT: decrease of porosity and increase of micro-hardness of work pieces from powdered high-speed steel.
