Abstract
Changes in phase composition and mechanical properties of sintered ZrO 2 + 3% (mole) Y2O3 specimens were examined after annealing in air and after various mechanical operations. Compacted ceramic specimens conta ining T and T' phase were obtained by sintering in a vacuum at 1800-de grees-C Ceramics containing T and T' phases have excellent toughness ( K1c up to 15 MPa . m1/2), bend strength up to 800 MPa and HV hardness up to 13 GPa.
