Effect of different binder phases on the Σ2 grain boundary plane distribution in cemented carbides
For WC–6 wt % Co and WC–6 wt % Ni composites, and by using five parameter analysis method as a new approach, the geometric and crystallographic features of carbide/carbide boundaries have been characterized. Two most frequently occurring WC/WC boundaries are 90° twist boundaries about [10-10] (Σ2 bo...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | For WC–6 wt % Co and WC–6 wt % Ni composites, and by using five parameter analysis method as a new approach, the geometric and crystallographic features of carbide/carbide boundaries have been characterized. Two most frequently occurring WC/WC boundaries are 90° twist boundaries about [10-10] (Σ2 boundaries) and 27.8° twist boundaries about [0001] (Σ13a boundaries), the Σ2 boundary populations vary with binder phase types, and carbide crystals are most frequently terminated by (0001) and (10-10) surfaces, such preference does not significantly alter if Σ2 boundaries are partitioned. |
