Abstract
σ = 2 grain boundaries in cemented carbide (WC-Co) were investigated by high-resolution electron microscopy on the atomic scale. The following crystallographic relationships were often obtained at the grain boundaries, these originating in the way that the interplanar spacings of the basal plane (0002) and the prism plane (1110) are quite close with a 2% misfit, since a/c ∼ 1: The role of Co in grain-boundary structures during sintering is discussed briefly.Keywords
