Abstract
This paper describes the effect of heat treatments on the microstructure and properties of iron powder specimens intended for ac soft magnetic applications at 60 Hz. The specimens were fabricated by compacting iron powder–lubricant (zinc stearate) mixes and heat treating the compacted specimens at 450–550°C in nitrogen. The microstructure and chemical characteristics of particle interfaces (X-ray photoelectron spectrometry) and the presence of microstrains (neutron diffraction) were correlated with the electrical and magnetic properties of the material. During the heat treatments (450–550°C), lubricant burns out and iron oxide contacts are created at particle interfaces (thermal oxidation bonding). Iron powder oxidation, which depends on the heat treatment temperature, reduces the electrical resistivity of the material and affects eddy current loss. The heat treatments modify the microstrains in the specimens and allow reduction of the hysteresis portion of the magnetic loss.

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
