Abstract Scope Soft magnetic alloys possess favorable functional properties, including high permeability/saturation induction, and low coercivity/core loss, which are beneficial for a variety of electromagnetic applications. However, many of these alloys suffer from poor mechanical properties that impede their manufacturing with conventional hot- and cold-working processes. We explore metal additive manufacturing (AM) as a rapid solidification method for producing bulk forms of magnetic alloys with unconventional compositions based in the Fe-Co-B-Cu-Zr and Fe-Si-Nb-B-Cu systems. Microstructure and composition of the AM-processed soft magnetic alloys, along with resultant mechanical and magnetic properties, are characterized and compared with conventionally processed materials. Implications of utilizing AM for developing next-generation soft magnetic materials and components will be discussed. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525
