Growth modes for monoclinic yttria‐stabilized zirconia during the martensitic transformation
Bibliographic record
Abstract
Abstract The tetragonal to monoclinic martensitic transformation of plasma‐sprayed 3 mol% Y 2 O 3 –ZrO 2 coatings is investigated by electron backscatter diffraction. The original metastable tetragonal phase shows an approximate “basal” texture with {001} t parallel to the coating surface. Based on the orientation analysis, plenty of monoclinic variants with atypical correspondence which indicates the c t axis transforms to the a m axis where (100) m //(001) t , (010) m , and (001) m //{110} t are clearly identified in addition to the correspondence where the c t axis transforms to the c m axis. Moreover, three growth modes are proposed and discussed according to strain accommodation. The observed sequential growth obeys the correspondence of the c t axis to the c m axis. Fourfold growth combines the correspondences of the c t axis to the c m and a m axes. The interleaving growth follows the correspondences of the c t axis to the c m axis within three tetragonal domains. These phenomena demonstrate the typical twin‐related and self‐accommodating configuration, which is in agreement with the phenomenological theory. These finding provide fundamental insight into the martensitic transformation mechanism and demonstrate a route for increasing the lifetime by controlling the tetragonal to monoclinic phase transformation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
