Microstructure characterization of high‐purity aluminum processed by dynamic severe plastic deformation
Bibliographic record
Abstract
Abstract Fine‐grained aluminum (700–1000 nm) was processed by dynamic severe plastic deformation of coarse‐grained (3 mm) pure aluminum (99.999 wt.%). The resulting microstructure was characterized by transmission electron microscopy (TEM) and X‐ray profile analyses. It is observed that the grain size determined by TEM departs from measurements made by X‐ray profile analysis. In the latter case, the average crystallite size determined over the global crystallographic or on the deformation‐induced texture components, namely {123} 〈 751 〉, {100} 〈 011〉, and {223} 〈 154 〉, yields similar values (∼225 nm). By contrast, the dislocation density determined on these texture components is about two times higher than the one measured on the global texture. The difference might be related to the specificities of the induced crystallographic texture.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
