Effect of chromium–sulphur interactions on decarburisation of levitated Fe–C alloy droplets by CO <sub>2</sub> –Ar gas mixtures
Bibliographic record
Abstract
This study provides an evaluation of the influence of chromium and sulphur on the decarburisation kinetics of Fe–Cr–C alloy droplets when exposed to argon gas mixtures containing carbon dioxide as the oxidant. For droplets containing the same amount of surface active sulphur, it was found that the decarburisation rate of iron–chromium droplets was substantially faster than that of chromium free alloys. This enhanced rate can be explained in terms of the attractive interaction between chromium and sulphur, which results in a decrease in the number of surface sites occupied by sulphur. An appropriate rate equation has been developed to characterise this behaviour. The findings from this work have beneficial implications with respect to the preferential oxidation of carbon rather than chromium when stainless steel is refined with argon–carbon dioxide gas mixtures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
