Abstract
The experiment of Pb-50wt%Sn,Pb-61.9wt%Sn alloy solidify in rotating magnetic field and the regularity of the process was carried out, The microstructure and growth characteristics were investigated. According to the cooling curves, The roating magnetic field tend to accelerate the cooling rate and stimulate the nucleation of the melt compared to static condition .The stirring effect of magnetic tend to provide some extra energy fluctutation to overcome the therm odynamic barrier for nucleation. It is found that,for Pb-61.9wt%Sn eutectic alloy,magnetic field induced the forced convection of the melt which result in a microstructure of lamellas →coarser lamellas→ anomalous eutecticand suppression of gravity-microsegregation and it was revealed that a “lamellar eutecticanomalous eutectic”.Meanwhile, for Pb-50wt%Sn eutectic alloy, a “dendrite manner spheric grain” microstructre change of the primary phase (Pb)occurs and conspicuous grain refinement effect takes place .These are explained by the forced convection inside the melt.

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.
