摘要：

Tape casting and hot-press sintering were used to fabricate an Al2O3/3Y-TZP laminated composite. In order to investigate the deformation properties, the as-prepared material was deep drawn at high temperatures. It was found that the microstructure of the material sintered at 1550 degrees C was fine and no significant pores were detected from SEM observations at the interfaces between the two types of layers. The superplastic forming experiment shown that, when the strain rate was constant, temperature had a great influence on the superplasticity of the Al2O3/3Y-TZP laminated composite. A hat-like part with the largest deformation height was obtained at 1500 degrees C.
