Research Abstract

In tetragonal ZrO_2.base oxides, material conditions were investigated for the occurrence of high-strain-rate superplasticity (HSRS) at lower temperatures. Even in undoped high-purity Y-TZP, HSRS was found to occur for a certain combination of the grain size and sintered density. For this combination, positive effects were limited for minor additions of other cations and for the dispersion of some cubic phases. For attaining HSRS at lower temperatures, fine grain sizes smaller than 0.2 μm is necessary in addition to nearly supersaturating cation doping or the dispersion of nonstoichiometric cubic phases. The results also indicated that a transition in the mechanisms of pore annihilation and growth is important for material processing and superplastic deformation, respectively.
