Abstract
The microstructural attributes of directionally solidified Ti-48Al-2Cr-2Nb (in at%) produced by the Power Down and Bridgeman techniques at various cooling rates/growth rates are presented. Fully lamellar α 2 -Ti 3 Al+γ-TiAl microstructures with y particles on grain boundaries are present in all conditions. The directionally solidified structure consists of discrete regions of columnar grains either parallel or radial to the growth direction, as well as a region of equiaxed grains. The phase structure and lamellar structure made by the two techniques are examined. Increasing the cooling rate or growth rate decreases the portion of columnar grains parallel to the growth direction and decreases the lamellar interface spacing.

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
