Abstract
Abstract In the present work, the microstructure and thermal stability of a commercial nanocrystalline aluminum alloy produced by combining equal channel angular pressing and ball milling followed by spark plasma sintering are characterized by X‐ray diffraction, optical microscopy, scanning electron microscopy and transmission electron microscopy. It is shown that the combination of different severe plastic deformation techniques, results to refining the grain size to a larger extent and improving the temperature range in which the grain size remains in the nanometer domain for temperatures as high as 400 °C. This broadens the scope of using the nanocrystalline aluminium alloy for high temperature industrial applications.

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
