摘要：

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 Sigma 2 twist grain boundaries between WC crystals using a double cantilever beam opened with a wedge under displacement control in a WC-10wt%Co sample. The fracture energy of this boundary type was compared with cleaving {10 (1) over bar0} 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 {10 (1) over bar0} plane and Sigma 2 twist boundaries, respectively.
