Popis:	Al 2 O 3 /ZrO 2 composites with from 0 to 100% ZrO 2 content were bonded by superplasic flow at 1280, 1350 and 1400 °C under the pressure 30 or 50 MPa during the time from several min to several hours. FGM joints between Al 2 O 3 and ZrO 2 parts and joints between non-superplastic coarse grained alumina bars with aid of thin superplastic plates were also obtained. All the joints were pore-free and strong. For Δ α > 1 × 10 −6 °C −1 cracks parallel to interface arose near the joint. Residual stress distribution was evaluated by finite-element and Vickers indentation analysis. The calculations revealed that critical tensile stresses appeared only in perpendicular direction to the interface.
