摘要：

For a wide range of stabilizer concentrations in yttria stabilized cubic zirconia (YSZ), Zr diffusion data extracted from published creep data and dislocation loop shrinkage data are discussed together with published Zr tracer diffusion data and our own data on Zr tracer diffusion in order to identify the most probable point defect responsible for Zr diffusion. From this evaluation, complex defects can be ruled out, as the single vacancy, V-Zr,(4') fits best. (C) 2000 Elsevier Science Ltd. All rights reserved.
