Abstract
AbstractThis study concerns the development of an experimental procedure to characterise the fatigue behaviour of NiTi shape memory alloy subjected to thermal cycling under a constant applied load. This experimental technique combines the measure of macroscopic properties with the X-ray analysis of the alloy structure. The evolution of transformation temperatures, total recoverable strain and hysteresis loops are measured up to 3000 heating and cooling cycles. The X-ray structural analysis performed under the same experimental conditions helps to understand the underlying mechanisms.Cette étude porte sur le développement d'une procédure expérimentale visant à caractériser le comportement en fatigue d'un alliage à mémoire de forme NiTi soumis à des cycles thermiques sous une contrainte appliquée constante. Cette approche expérimentale combine la mesure des propriétés macroscopiques sur un banc d'essai avec l'analyse par rayons X de la structure de l'alliage. L'évolution des températures de transformations de phases, l'effet mémoire et les boucles d'hystérésis sont mesurés jusqu'à 3000 cycles thermiques de chauffage et de refroidissement. L'analyse par rayons X de la structure dans les mêmes conditions expérimentales permet de comprendre les mécanismes en jeu.

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
