Phase Relationships in the Zn-Rich Corner of the Zn-Fe-Zr System
Bibliographic record
Abstract
The phase relationships in the Zn-rich corner of the Zn-Fe-Zr system at 450, 600 and 800 °C were investigated by means of x-ray powder diffraction (XRD) and scanning electron microscopy coupled with energy/wave dispersive spectroscopy (SEM-EDS/WDS). Two ternary compounds were found in the system. One of them was designated as ZrFe 2 Zn 20 according its narrow composition range. It is a CeCr 2 Al 20 -type compound with lattice parameter a = 1.3941 nm. ZrFe 2 Zn 20 is stable below 878.6 °C and can co-exist with all binary compounds in the Zn rich corner of the system. The other one was designated as Zr 2 Fe 3 Zn 5 . SEM-WDS analysis indicated that Fe was hardly detected in ZrZn 22 , Zr 5 Zn 39 and ZrZn 3 . And no Zr was dissolved in all Fe-Zn intermetallic compounds.

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.
