Abstract
The grain boundary network of WC in WC-Co is important, as cracks often travel intergranularly. This motivates the present work, where we experimentally measure the fracture energy of Σ2 twist grain boundaries between WC crystals using a double cantilever beam (DCB) opened with a wedge under displacement control in a WC-10wt%Co sample. The fracture energy of this boundary type was compared with cleaving {101 ̅0} prismatic planes in a WC single crystal. Fracture energies of 7.04 ± 0.36 Jm-2 and 3.57 ± 0.28 Jm-2 were measured for {101 ̅0} plane and Σ2 twist boundaries respectively.
