The influence of an oxidizing atmosphere on the high-temperature plasticity of zirconia/nickel cermets has been studied by conducting creep tests in air. The resulting microstructure has been characterized by scanning, conventional and high-resolution electron microscopy. Despite the large microstructural changes, the composites do not exhibit mechanical degradation.
Plastic deformation at elevated temperatures (1300-1450°C) of 3 and 4 mol% Y 2 O 3 -stabilized ZrO 2 polycrystals with fine grain size (d < 1 μm) has been studied at very low stresses (< 10 MPa). Extensive internal cavitation has been found for a few percent of strain, instead of the superplastic behavior exhibited by these materials at intermediate and high stresses,...
