Abstract
Low temperature superplastic behaviour (1100-degrees-C) was demonstrat ed in creep compression tests of three different CuO-doped yttria stab ilized tetragonal zirconia polycrystalline (YTZP) materials, synthesiz ed using commercially available powders. The microstructures obtained were analysed by different characterization techniques such as ceramog raphy, impedance spectroscopy, transmission electron microscopy and X- ray diffraction. Although some observations point to the formation of a thin liquid phase which could explain the low temperature superplast icity of these CuO-doped YTZP materials, such a phase could not be det ected.
