Symposium Phase Transformations in Ceramics: Science and Applications
Presentation Title Realizing Novel Defect Ordering in Yttria Stabilized Zirconia via Ion Radiation
Author(s) Jessica A. Krogstad
On-Site Speaker (Planned) Jessica A. Krogstad
Abstract Scope Yttria-stabilized zirconia (YSZ) has been shown to be very resistant to phase transitions or amorphization under ion irradiation. Most of these studies have either focused on low ion energies (<4 MeV) or very high ion energies—hundreds of MeV or even GeV. Naturally, these different ion energies produce different effects within the material. The intermediate or medium ion energy range has been largely overlooked but holds the potential for unique interactions. This work aims to leverage these ion beam material interactions to develop processing routes towards novel functionality. Preliminarily observations via electron diffraction in transmission electron microscopy (TEM) have shown sublattice vacancy ordering in cubic YSZ under 45 MeV gold ion irradiation. This presentation will explore the relationship between ion energy, dosage and the likelihood of sublattice ordering, as well as the overall thermal stability of the ordered structure and preliminary efforts to correlate ordering with functional transport properties.
