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 distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
