Abstract
The development of additive manufacturing (AM) of permanent magnets is rapidly growing due to the competitive advantages they offer. AM of complex shape magnets could revolutionize the design of electrical machines potentially allowing for higher performance. Unfortunately, magnetic performance of AM permanent magnets is often limited due to the use of isotropic powders. In this study, Al-NdFeB composite permanent magnets were fabricated by cold spray AM using anisotropic NdFeB powders. Anisotropic powder can improve magnets’ remanence and energy product via particle alignment and subsequent magnetic anisotropy. The effect of gas temperature on deposition rate and magnet performance was evaluated. Magnetic measurements were performed along three orthogonal directions to quantify the level of anisotropy. It is demonstrated that anisotropic powders partially align itself during the cold spray process in the absence of external magnetic field. This could pave the way for a simple and efficient way of fabricating anisotropic magnets.

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
