Some Aspects of Nitrogen Addition and Removal During Special Melting and Processing of Iron and Nickel Base-Alloys
Bibliographic record
Abstract
In this work we review the published information on the exchange of nitrogen across the gas/metal interface in the case of liquid iron-and nickel-base alloys.Although the thermochemistry of these systems is reasonably well-established, it is clear that the kinetics of the reactions involved are rather complex and hence not as well defined.The role of precipitated nitrides is also considered, since this feature is an integral part of the use of filters as well as being a core facet of the nitride removal reaction in several of the processes surveyed.We also review the present position in respect of the production of high-nitrogen alloys, including the role of systems relying on the presence of N + ions to establish concentrations greater than those predicted by Sieverts' Law.We conclude that the basic information needed to establish a rational production route for any given alloy affected by nitrogen content is available, but that a very careful consideration of all the factors involved is required before defining such a route.

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.
