Abstract
Assessing the mechanical properties of in-service pressure vessels is essential to ensure their safe and continued operation. 1Cr-1/2Mo steel samples are collected from pressure vessels with different years of service exposure. Sub-size flat tensile specimens are tested, and the results show that with an increasing service exposure time, samples exhibited an increased strength, but a decreased ductility compared to the original material. Precipitation of nanoscale carbides within the ferrite/bainite grains has contributed to strengthening the material while the decrease in ductility is believed to be caused by larger size discontinuous carbide particles on the grain boundaries.

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
