Abstract

The phases, transformability, microstructure and mechanical properties of ZrO2-Gd2O3 polycrystals containing 1.75–8 mol% Gd2O3 were studied. The samples were prepared by a coprecipitation route followed by sintering at 1400°C for 2 hours. The grain size was in the range of 0.1–0.2 μm except for some large grains at high Gd2O3 contents. Only a tetragonal phase was observed between 2–4 mol% Gd2O3 and a cubic phase for compositions containing ≥9.6 mol% Gd2O3. A peak K IC of 12 MPa m1/2 and a strength of 800 MPa were obtained in the 2 mol% Gd2O3 alloy for which the t → m transformation on the fracture surface was also found to be maximum. Transformation toughening is able to account for most of the toughness of the samples.
