| Abstract Scope |
FeCo-based alloys are uniquely suited for application in high-efficiency electric motors, generators, and power conversion systems, due to their exceptional saturation magnetization, elevated Curie temperature, and low coercivity. However, B2 ordered phase formation during conventional processing of these alloys severely limits ductility, machinability, and geometric design freedom. Additive manufacturing, specifically laser powder bed fusion (LPBF), can potentially overcome these barriers through near-net-shape fabrication with precise microstructural control. This study focuses on LPBF processing of Fe-49Co-2V (Hiperco) with the as-built condition exhibiting near-gigapascal tensile strength with appreciable ductility (~10%), but relatively high coercivity (~21Oe). The high ductility is likely due to the suppressing of B2 ordering in the as-built condition. Subsequent short-duration annealing drives recrystallization and controlled B2 ordering, dramatically reducing coercivity (~2Oe) and eddy current losses, while embrittling the alloy. The mechanistic origins of these two thermally selectable property states will be discussed in this talk. |
