Spark plasma sintering (SPS) technique is being widely used to produce nanocrystalline materials by virtue of rapid sintering at relatively lower temperatures. In this investigation, fully dense Al 2 O 3 –ZrO 2 –MgAl 2 O 4 composite was superplastically formed into a complex shape using SPS equipment with a strain rate of approximately 10 −2 s −1 at temperatures as low as 1150°C which is impossible to obtain by using conventional forming methods. Furthermore, a powder compact can be directly shaped into a complex shape, combining sintering and forming into one step. The product is fully dense and free of surface cracks. These results indicate that SPS can be a very competitive forming tool for ceramics as well other hard materials.
