Abstract

fetched live from OpenAlex

In this work, the impact of deep cryogenic and tempering treatment on the corrosion behavior of AISI 420 (UNS S42000) and AISI 52100 (UNS G52986) steel in 3.5% sodium chloride (NaCl) and sodium bicarbonate (NaHCO3) + 0.25% NaCl solution was studied using open-circuit potential (OCP), potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) measurements. The relationship of microstructure and the electrochemical response of differently treated samples was discussed. The results indicated that, compared with the conventional treatment, no significant modification of the electrochemical corrosion behavior after cryogenic treatments was observed. No passive behavior was observed for either AISI 420 or AISI 52100 in 3.5% NaCl, whereas it was observed in NaHCO3 + 0.25% NaCl solution. Different effects of tempering treatment on the corrosion behavior between AISI 420 and AISI 52100 were observed due to different modifications of the microstructure during the tempering process. The amount of retained austenite has a critical role in determining the pitting resistance. The pitting resistance increased with the amount of retained austenite.

Teacher imitation

Not 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.
