| Abstract Scope |
Samarium–iron–nitride (Sm–Fe–N) bonded magnets have emerged as promising candidates due to their exceptional magnetic properties. In this study, powders comprising 95 wt.% SmFeN (~74 vol%) embedded in a polyamide-12 binder were processed via batch mixing and compression molding. These magnets achieved a 99 % degree of alignment with post magnetic field annealing and a high energy product of 186.21 kJ·m⁻³ (23.4 MGOe). Efforts are also underway to achieve in situ alignment of magnetic particles during additive manufacturing, utilizing integrated magnetic field sources directly within the printing process. These findings provide valuable insights into how microstructural alignment and binder dynamics influence the magnetic strength and performance of high-loading bonded magnets |
