Abstract
A layer by layer analysis of rails, differentially hardened in various modes, has been carried out using transmission electron microscopy on various scale levels. It has been shown that the differential hardening of rails is accompanied by the formation of a morphologically different structure, which is formed according to the diffusion mechanism of γ-α transformation and consisting of plate perlite grains, free ferrite grains, and grains of a ferrite-carbide mixture. The gradient character of modifications of structure, phase composition, and dislocation substructure parameters along the cross section of rail head has been established. It has been revealed that the interfaces between globular cementite particles and the matrix are the most dangerous stress concentrators.

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
