Abstract
⺠Vacuum sintering of WC-Co hardmetals produced from nanocrystalline WC powders is accompanied by their partial decarbonizing. ⺠The loss of carbon is observed already at minimum sintering temperature 800 °C and leads to an appearance of ternary carbide phases in hardmetals. ⺠Large density and uniform homogeneous microstructure are reached in nanostructured hardmetals at smaller sintering temperature than these in the hardmetals produced from coarse-grained WC powder. ⺠Use of nanocrystalline WC powder allows decreasing of the optimal sintering temperature of the WC-Co hardmetals by about 100 °C.
