| 摘 要： | 采用流延制膜和热压烧结工艺制备了Al2O3 / 3 Y-TZP 层状复合材料。用SEM 观察显微组织, 并采用高温深拉实验对该材料进行了超塑性能研究。结果表明: 1550 ℃热压烧结制备的材料晶粒细小, 界面结合良好;当应变速率一定时, 变形温度对Al2O3 / 3Y-TZP 层状复合材料的超塑性能具有重要影响, 1500 ℃时得到深拉成形最大高度, 温度较高和较低时超塑性能均会降低。

| 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. |
