Abstract
Superplastic behavior has been recognized in ceramics only recently. In this study, the deformation and microstructural characteristics of a 2 mol% yttria stabilized zirconia were examined in both tension and compression. For a given batch of material, the zirconia exhibited identical mechanical characteristics in tension and compression. The significant differences in mechanical behavior from batch to batch were rationalized on the basis of variations in impurity levels, as determined by optical emission spectroscopy. There was considerable cavitation during tensile deformation, and quantitative evaluations indicated that the number density of cavities increased with increasing imposed stress.
