Abstract
With the expanding use of high-performance permanent magnets, such as Nd-Fe-B, in green energy production and e-mobility, comes the need to further investigate contemporary production methods. Field assisted sintering technologies, such as spark plasma sintering and flash spark plasma sintering, have shown promising results with regards to anisotropic texturing, densification, and microstructural fine-tuning, even from non-ideal crushed anisotropic Nd-Fe-B scrap as a starting powder. Optimization of these processes could lead to magnetic performance that matches or exceeds standard commercial magnet production techniques, such as hot deformation. This is due to the fine parameter monitoring and control available with field assisted sintering devices. This study focuses on the optimization of field assisted sintering with commercial MQU-F to demonstrate net-shaping of anisotropic Nd-Fe-B magnets with an intention of transferring the parameters to the deformation of recycled magnet powder.

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 it
