Abstract
The role of anion (oxygen) vacancies on the low temperature degradation of Y-TZP and a carburized Y-TZP has been investigated under a high strength electric field. It is found that the stability of a Y-TZP, but not a carburized Y-TZP was decreased when a high strength electric field was applied. The volume fraction of monoclinic phase produced by the electric field increased in a parabolic rate law manner which shows that the transformation is controlled by a diffusion process. It is indirectly shown that the low temperature degradation of Y-TZP results from the diffusion and migration of oxygen vacancies. The effect of temperature at a constant electric field on the degradation shows that the transformation can be promoted only in a specific temperature range. The stronger stability of carburized Y-TZP can be attributed to the nature of carbon in the Y-TZP lattice, where it exists in interstitial sites as a atom, rather than an ion.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
