Abstract
Electrospark deposition (ESD) was applied to Al–Zr binary system in order to study the possible change of solidification structure from the stable D023 tetragonal equilibrium phases to the cubic L12, when high cooling rates and undercooling conditions are involved. The results show that a supersaturated solid solution was formed for the alloy containing 0.5 at%Zr, while a two-region layered structure was developed for the alloys with 1–1.5 at%Zr. These layers are composed of refined equiaxed grains, with a smaller particle size distribution for the region where the L12 precipitates were present.

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
