FIELD: metallurgy.
SUBSTANCE: proposed process comprises sintering of carbide-bearing alloys at 1400-1650°C and cooling down. After sintering, vacuum annealing is performed with heating to 1050°C-1250°C and holding for 1 hour. Cooling down is carried our jointly with the furnace for 4 hours.
EFFECT: higher hardness.
