Abstract
The corrosion response of heat-treated C63020-NAB alloys fabricated through laser-powder bed fusion (L-PBF) and laser-directed energy deposition (L-DED) techniques was assessed in NaCl solution on surfaces parallel and perpendicular to their building direction. Microstructural analyses revealed a stronger texture formed in the L-PBF NAB, while the L-DED NAB exhibited a slightly more isotropic behavior characterized by a finer microstructure and more equiaxed grains on both surfaces. Corrosion performance analysis indicated isotropic corrosion behavior in both L-DED and L-PBF NAB, though the L-DED NAB showed marginally better corrosion resistance. The microstructural characteristics were identified as the primary factor driving the passivity and corrosion resistance of the alloy.

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
