Influence of oxygen impurities on the crystallization mechanism of NiZr2 metallic glasses
Bibliographic record
Abstract
The influence of oxygen impurities on the crystallization mechanism of NiZr2 metallic glasses was studied. For this glass system, the first crystallization product is the metastable E93(cF96) cubic structure instead of the equilibrium C16(tI12) tetragonal structure. A possible mechanism for the formation of this metastable phase has previously been put forth. The hypothesis is that oxygen forms a semipermanent bond with Zr resulting in the oxygen atom being surrounded by six Zr atoms in octahedral configuration which act as nucleation sites for the E93 cubic phase. Hydrogenation of the amorphous composition eliminates the nucleation sites required for the formation of this metastable cubic phase, thereby allowing the glass to crystallize directly into the stable tetragonal C16 phase, and thus providing strong evidence in support of the proposed crystallization mechanism.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
