Deformation and fracture processes and the physical metallurgy of WC–Co hardmetals

AbstractDeformation and fracture processes have been examined in WC–Co tool materials, still the most commonly used hardmetal. The relevant microstructural parameters are described in detail and an assessment is made of their effects on strength and fracture tests at ambient temperature, for the constituent phases separately and in combination. The results of properties more relevant to service behaviour, such as fatigue and creep, are summarised. Finally, recommendations are made with regard to the need for further fundamental research.
