The Assimilation Mechanism of Mn-Al Compacts in Liquid Mg
Bibliographic record
Abstract
This paper describes the assimilation mechanism of Mn-Al compacts in liquid Mg, utilizing procedures that have been employed successfully in studying assimilation mechanisms in other liquid metals. Two critical steps were identified in the assimilation process: (1) melting of some Mn-Al reaction products and (2) mass transfer of phases with the high Mn content from the reaction sites into the Mg bath. The assimilation process was divided into three stages: incubation stage, intermetallic reaction stage, and homogenization stage. Compact swelling was observed during the intermetallic reaction stage. Yet, contrary to the currently-held prevalent view, it was determined that compact swelling was not due primarily to the formation of new intermetallic phases. Rather, swelling is due to the existence of a large amount of porosity initially in the compact which becomes greatly augmented with the large heat released during the Mn-Al exothermic intermetallic reactions.

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.
