Abstract: Al₂O₃ / 3Y-TZP laminated composite was fabricated using the tape casting and hot-press sintering. Themicrost ructure was observed by SEM. The as-received material was deep-drawn at high temperatures to research it ssuperplasticity. The result s show that the microst ructure of the material sintered at 1550 ℃has fine grain and st ronginterfaces. When the st rain rate is constant, the forming temperature has great influence on the superplasticity ofAl₂O₃ / 3Y-TZP laminated composite. The greatest deformation height of deep-drawing was obtained at 1500 ℃. Itis worse at higher or lower forming temperatures.
