PRODUCTION OF CUTTING TOOLS FROM CARBIDE-BEATING ALLOYS OF TUNGSTEN AND TITANIUM-TUNGSTEN GROUPS

摘要

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.;8 dwg, 5 tbl
