Microstructure and creep resistance of Mg–10Zn–4Al–0.15Ca permanent moulding alloy
Bibliographic record
Abstract
In this paper, the microstructure of Mg–10Zn–4Al–0.15Ca (wt-%) (ZAC104015) magnesium alloy was characterised in the as cast condition. Thermal analysis was performed to determine the liquidus, solidus, and intermediate reactions that occur upon cooling. The results show that this alloy is composed of α-Mg and two intermetallic phases containing calcium τ'1 and τ'2. These two intermetallic phases have the same type of crystal structure as that of phase τ (Mg32(Al,Zn)49). The thermal stability of the phases τ, τ'1, and τ'2, were also evaluated. This experimental study indicates that the phase τ'2 is more stable than τ and τ'1 at elevated temperature and directly related to creep resistance improvement.

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.
