Abstract
The exceptional mechanical and tribological behaviour of cemented carbides (WC–Co) is largely attributed to their microstructure, consisting of two phases exhibiting totally different properties at the local level. However, information on the microstructure/micromechanical properties relations for these materials is limited, especially when accounting for the constraint level exerted by the surrounding carbides on the metallic binder. In this work, a systematic procedure to evaluate the correl...
