| Abstract Scope |
The soft magnetic phase of iron nitride (γ’-Fe4N) can extend soft magnetic performance boundaries within a broad set of applications. With a magnetization slightly greater than silicon steel and an electrical resistivity at least an order of magnitude higher than Si steel, iron nitride can increase overall efficiency while maintaining or even improving power density in a wide range of devices. Taking advantage of the low consolidation temperatures of spark plasma sintering (SPS), we have demonstrated a path for consolidating raw powders of iron nitride into both bulk and composite parts. Iron nitride powder processing and preparation methods will be discussed in addition to the details of SPS consolidation. The fabrication of iron nitride based soft magnetic composites leveraging the same powder processing methods as for SPS will also be covered. |
