Abstract
In this study, SiC nanoparticles (∼50 nm, 3 vol%) are homogenously incorporated within an Al–Mg alloy metal matrix during multi-step friction-stir processing (FSP) to fabricate an Al-matrix surface nanocomposite. A fundamental understanding is developed, correlating microstructural features and crystallographic textural components in the context of the material flow pattern and operative dynamic restoration phenomena using electron backscattering diffraction and high resolution-transmission electron microscopy analysis. The annealed base metal does not contain any preferred orientation and its texture is completely random. Incorporation of SiC nanoparticles via FSP results in significant grain structural refinement down to the size of ∼1.4 µm and changing the textural component towards the Goss/Cubic and P1/P2 dominant fibre components in the centre of stirred zone.

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
