Abstract
The corrosion behavior of the FeCrNi medium-entropy alloy (MEA), additively manufactured using laser powder bed fusion (LPBF), were investigated in this research. Compared with the LPBF 316 L stainless steel (SS), the LPBF FeCrNi MEA shows a superior corrosion resistance in the 3.5 wt% NaCl solution. The Cr 2 O 3 -rich passive film formed on the LPBF FeCrNi MEA has fewer defects, better self-repairing ability, and consequently a stronger protective property than that of the LPBF 316 L SS. The high value of Cr/Fe ratio in the passive film, caused by the supersaturated Cr (>30 at%) and the refined microstructure (increased grain boundary density), is the main reason for the superior corrosion resistance of the LPBF FeCrNi MEA.

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
