| Abstract Scope |
Soft magnetic alloys exhibit high magnetic permeability/saturation induction and low coercivity/energy loss, yet they are limited by poor mechanical properties except in the nanocrystalline grain size regime, which is difficult to access via conventional manufacturing processes. In this study, additive manufacturing (AM) was used as a rapid solidification technique for producing bulk forms of an Fe-Si-B-Nb-Cu soft magnetic alloy that is traditionally manufactured as melt-spun amorphous/nanocrystalline ribbons. Pre-alloyed powder feedstock in the form of micron-scale flakes was ball milled from nanocrystalline ribbons. Compact metallurgical specimens were fabricated using both laser directed energy deposition (L-DED) and laser powder bed fusion (L-PBF) AM processes. Alloy microstructure, mechanical properties, and magnetic properties were characterized and rationalized based on differences in the AM processes and compared to conventionally processed product ribbons.
