Abstract
The effect of sintering temperature and particle size of WC carbide powders on phase composition, density, some mechanical properties, and microstructure of WC–Co hardmetals is discussed in this chapter. Sequence of phase transformations during sintering of hardmetals is considered in detail. The use of nanocrystalline WC powders is shown to reduce the optimal sintering temperature of the WC–Co hardmetals by about 100 K.
