CHARACTERIZATION OF A-319 ALUMINUM THROUGH THE ADDITION OF MASTER ALLOY AL-MG-CE APPLYING MECHANICAL AGITATION
Bibliographic record
Abstract
The influence of cerium (Ce) on the as-cast microstructure and mechanical properties of the A-319 alloy were investigated.The A-319 experimental alloys were prepared.The aluminum,magnesium, cerium master alloy was added into the molten bath The cerium content increased 0 to 0.12 wt.% after 15 min of treatment.To obtain kinetic information and metallographic, samples were analyzed by using Scanning Electron Microscope (SEM) respectively.Dross samples were taken and analyzed by X-ray diffraction (XRD) for the qualitative identification of the crystalline compounds.The tensile properties, including ultimate tensile strength, yield strength.Elongation and creep properties of the as-cast experimental alloys were established.This result indicate that the incorporation of Ce to the A-319 alloy cause change in the morphology and distribution of the phase.Nevertheless, the grain size tended to be effectively refined.Furthermore, adding 0.12 wt.% Ce to the A-319 alloy improves the tensile properties at room temperature.

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.
