Tensile and cold-rolling properties of high-purity Mg-3mass % Al-1mass % Zn alloy
Bibliographic record
Abstract
A high-purity AZ31 magnesium alloy containing no manganese was prepared using distilled magnesium (>99.99%). The tensile and cold-rolling properties were then examined and compared with a commercial-purity AZ31 magnesium alloy. The high-purity alloy exhibited excellent tensile ductility and cold-rolling workability. It achieved a cumulative reduction of 20% with a high surface finish before cracks formed. It was found that the high-purity alloy deformed more uniformly, showing twin deformations distributed evenly across the specimen, while the commercial alloy contained highly deformed regions resulting in early crack formations. Due to the high amount of cold reduction and uniform deformation characteristics of the high-purity alloy, the annealed specimen exhibited a recrystallized structure with a fine, uniform grain size of 2 μm.

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.
