Mécanismes de durcissement structural des alliages plomb-cadmium-strontium pour les grilles de batterie
Bibliographic record
Abstract
Le vieillissement des alliages plomb-strontium sursatures trempes se fait principalement en une seule etape qui correspond a un mecanisme de transformation discontinue. Apres le vieillissement une nouvelle transformation discontinue prend naissance, elle est caracterisee par une precipitation lamellaire PbSr 3 . Le vieillissement des alliages plomb-cadmium est caracterise par une precipitation continue et une transformation discontinue. Quant a leur survieillissement, il est caracterise par une transformation discontinue avec precipitation de cadmium pur a partir des fins precipitees durcissants de la meme phase. Notre objectif est donc d'etudier les mecanismes de durcissement structural des alliages plomb-cadmium-strontium. Deux etats structuraux sont consideres: alliage brut de coulee et alliage rehomogeneise. Les temperatures explorees sont essentiellement 20 et 80°C. Cette derniere temperature est choisie parce qu'elle correspond a la temperature de murissage des plaques des batteries ainsi qu'a la temperature extreme de son fonctionnement. Les teneurs en cadmium sont 2 et 3,2%, et celles du strontium sont 0,08 et 0,12% en poids.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
