Abstract
and are two important protective oxides on the surface of austenitic alloys used for ethylene cracking. This investigation is focused on the effect of on the stability of and in high temperature carbonaceous environments. The presence of in increased the carburization rate of the spinel through the formation of , which accelerates the decomposition of . was formed when was added to . Compared with , appears more stable. However, can be further decomposed to and chromium carbide in high temperature carbonaceous environments. The latter quickly formed nanosized carbides, which induced coke formation during increased exposure in carbonaceous environments. In carbonaceous environments with higher oxygen partial pressures, the detrimental effect of on the carburization resistance of the spinel and is alleviated because of the suppression of formation, thereby preventing coke formation.

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
