The addition of Al2O3 to Y2O3-partially stabilized ZrO2 submicrometer powders consolidated by isostatic hot pressing was noted to yield a substantial increase in bending strength. Average bending strength for a 20-percent Al2O3 Y2O3-partially stabilized ZrO2 composite was 2400 MPa, with a fracture toughness of 17 MN m to the -3/2. Microindentation and chevron-notched beam test method results are presented. 9 references.
