Abstract
Laser-ultrasonics is a non-destructive and non-contact technique that can characterize many microstructural and elastic parameters of materials and is suitable for on-line applications. In this paper, cold-rolled samples of an Al-Mg alloy (AA5754) are annealed in a Gleeble thermomechanical simulator at various temperatures (275°C, 300°C, 325°C and 350°C). The recrystallization kinetics is monitored in-situ and in real time by laser-ultrasound. It is found that longitudinal velocity variations correlate well with the recrystallized fraction, as evaluated by metallography and mechanical testing on samples submitted to similar thermal cycles.

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
