Abstract
⺠The hot-pressed ZrB2 ceramics with WC additive exhibited the superplastic behavior at 1900 °C. ⺠On the tensile side of deformed sample, many cavitations were observed at the multigrain junctions and the fracture surface was relatively flat. ⺠On the compressive side, very little cavitations occurred and some large cracks existed in the fracture surface. ⺠The presence of a secondary W-containing phase formed by the addition of WC, prohibited the coalescence of cavities by its plastic deformation.
