Lattice and grain boundary diffusion of cations in tetragonal zirconia
Zirconia is a widely used oxide ceramic in various high performance applications due to its attractive mechanical, electrical and thermal properties. In particular, the material 3 mol% yttria stabilized tetragonal zirconia (3YTZ) has been shown to undergo superplastic deformation [1]. One crucial step in the understanding of processes like superplasticity involves the knowledge of appropriate c...
متن کاملAes/stem Grain Boundary Analysis of Stabilized Zirconia Ceramics
A~~act-Semi~uantitative Auger Electron Spectroscopy (AES) on pure monophasic (Z~*)~.~(YO,.~~,,, was used to determine the chemical composition of the grain boundaries. Grain boundary enrichment with Y was observed with an enrichment factor of about 1.5. The difference in activation energy of the ionic conductivity of the grain boundary compared with the bulk can be explained by the Y segregatio...

متن کاملThe relationship between grain boundary structure, defect mobility, and grain boundary sink efficiency
Nanocrystalline materials have received great attention due to their potential for improved functionality and have been proposed for extreme environments where the interfaces are expected to promote radiation tolerance. However, the precise role of the interfaces in modifying defect behavior is unclear. Using long-time simulations methods, we determine the mobility of defects and defect cluster...
متن کاملAtomic-Resolution STEM-EDS Mapping of Grain Boundary Solute Segregation in Yttria-Stabilized Zirconia - RETRACTION.
Yttria-stabilized zirconia (YSZ) is one of the primary choices for the electrolyte material in solid oxide fuel cells (SOFC), due to its excellent ionic conductivity at high temperatures. Nevertheless, such performance is usually limited by the ionic conductivity at grain boundaries, which is at least two orders of magnitude lower than that of bulk [1]. As a result, many studies have been perfo...
