Abstract
In a previous investigation, a combined addition of zirconium and lanthanum was found to confer more marked grain refining than zirconium alone. The present experimental study confirmed this result. However, in this study, the microstructure was examined with more attention to the form of the zirconium-rich coring in the grain refined structures. It was concluded that although the average apparent grain size decreases with an addition of lanthanum, this is in part because grain growth takes place in the Mg–Zr alloy, while the suppression of grain growth occurs with an addition of lanthanum as small as 0.5%.

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
