three al2o3/zro2 composite series, containing o, 2 and 7.5 mole y2o3, were fabricated for fracture toughness determinations. without y2o3 additions, 2 m/o y2o3 allowed full retention up to 60 v/o zro2 cubic zro2 was produced with additions of 7.5 m/o y2o3. significant toughening and strengthening was achieved when tetragonal zro2 was present.
