説明

<jats:p> Composites of Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> and Y <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> partially‐stabilized ZrO <jats:sub>2</jats:sub> were isostatically hot‐pressed using submicrometer powders as the starting material. The addition of Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> resulted in a large increase in bending strength. The average bending strength for a composite containing 20 wt% Al <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> was 2400 MPa, and its fracture toughness was 17 MN·w <jats:sup>−3/2</jats:sup> </jats:p>
