摘要：

The influence of diffusion creep in the superplastic deformation of 3 mol% polycrystalline yttria-stabilized tetragonal zirconia was investigated. Comparison of several data suggested that both high and low purity specimens exhibited essentially identical strain rates and deformation behavior of n = 2, p = 3 at high stresses, and n = 3 and p = 1 at low stresses.
