Abstract
The effects of chemistry, reduction ratio and annealing cycle on edge breaks/Lüder lines during cold mill processing of commercial and drawing quality low-carbon steels have been investigated. It is possible to eliminate Lüder bands and associated yield-point elongation (YPE) by producing interstitial free steels that do not contain any free C or N. In low-carbon steel, however, it is necessary to develop other strategies for reducing Lüdering and YPE. Reduction ratios and annealing cycles that resulted in a uniform, completely recrystallised microstructure were ineffective at reducing YPE. It was determined that the most promising approach for reducing YPE in steels containing free interstitials is to develop a heterogeneous microstructure. This was achieved through abnormal grain-growth in the full-recrystallised material to create a bimodal grain-size distribution. The implications for the production of commercial and drawing quality low-carbon steels are discussed.

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
