FIELD: metallurgy.
SUBSTANCE: method includes sintering of powder in a furnace at a temperature ranging from 1360 to 1550°C to produce product and its cooling. Cooling of the product is carried out together with the furnace to 950°C, then the product is cooled to 800°C with a speed of 1.0°C/minute to 3.5°C/minute, then the product is cooled with the furnace to the room temperature.
EFFECT: improvement of hard alloy products quality due to the production of more fine and uniform structure of the hard alloy.
