| Abstract Scope |
Soft magnetic alloys produced by additive manufacturing can overcome many of the challenges associated with conventional metallurgical processing. Functional grading between brittle Fe-Co (BCC) and lower-saturation Ni-Fe (FCC) alloys through laser engineered net shaping (LENS) can enhance functional properties beyond those of the individual alloys. This work focuses on how grading between Fe<sub>49</sub>Co<sub>49</sub>V<sub>2</sub> and Ni<sub>80</sub>Fe<sub>16</sub>Mo<sub>4</sub> affects the microstructure, crystal structure, and magnetic properties. Grading results in a refined microstructure, however, post-build thermal treatments are found to promote recrystallization and grain growth, leading to improved magnetic properties. Analysis of the crystal structures provides an understanding of the solubility limits between the BCC and FCC structures. Success in functional grading of these soft magnets provides a pathway towards improved power conversion efficiency and application of multimaterial additive manufacturing.
