Carbide grain growth in cemented carbides
Acta Materialia, 2011Abnormal grain growth is often observed in cemented carbides during sintering, but cannot be understood in terms of the classical LSW theory.

Reinforcement of tungsten carbide grains by nanoprecipitates in cemented carbides
Nanotechnology, 2016In contrast to the conventional method that obtains a high fracture strength of tungsten carbide-cobalt (WC-Co) cemented carbides by reducing WC grain size to near-nano or nanoscale, a new approach has been developed to achieve ultrahigh fracture strength by strengthening the WC grains through precipitate reinforcement.

Microstructures of cemented carbides
Materials & Design, 2001Abstract An overview is given of the detailed microstructure of cemented carbides of types WC–Co and WC–MC–Co and of titanium carbo-nitride based cemented carbides (cermets). The manufacturing process is first descibed, and the changes in composition that occur during manufacturing are discussed.

AbstractCemented carbides belong to a class of hard, wear-resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a ductile metal binder. Cermet refers to a composite of a ceramic material with a metallic binder.
