抄録

To develop a new attractive ceramic material in which both high strength and high toughness might be achieved, we have established the new concept of an interpenetrated intragranular nanostructure based on the general design of the nanocomposites. The composite system designed according to the above concept possesses a novel microstructural feature. That is, for the composite composing of A and B phases, either nanometer sized A particles or equivalent sized B particles locate within the micron sized B grains or A grains, respectively. By applying the above material design, we succeeded to achieve a simultaneous improvements in strength and toughness for both Y-TZP and Ce-TZP based composite systems. This progress breaks through the strength-toughness tradeoff relation essentially existing in transformation toughened zirconia and its composite materials. In this paper, realized interpenetrated intragranular nanostructure along with forming process and mechanical properties will be described.
