Abstract
The influence of impact shock-loading was investigated on the mechanical behaviour, microstructure evolution, and texture of a new high-Mn steel. The mechanical behaviour of the shock-loaded specimen was compared with quasi-static compression condition. A Hopkinson pressure bar setup was used to perform the high-strain-rate deformation. Continuous yielding was observed under both low and high-strain-rate deformation. The yield stress also illustrated a positive strain-rate sensitivity with increasing strain-rate. An obvious increase in the flow stress of the steel was detected at higher strain-rate. A strain hardening followed by a strain softening was detected in stress–strain curve after shock-loading. Electron backscatter diffraction also displayed the activation of strain-induced ϵ-martensite and ά-martensite while deformation twinning was absent at high-strain-rate.

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
