Iron nitrides (FexN) have magnetic moments well in excess of those achievable with currently available soft magnetic materials. There are, however, few reports involving the fabrication of dense FexN using powder, partly because of the relatively elevated sintering temperatures required which can lead to decomposition of FexN. In present study, fully dense bulk FexN was synthesized for the first time ever using spark plasma sintering (SPS) of FexN powders. The microstructure of consolidated bulk FexN was characterized with XRD, SEM, and TEM, and their magnetic properties were measured and will be discussed. The X-ray diffraction studies revealed a mixed phase composition. Finite element method (FEM) was also applied to investigate and explain localized heating and temperature distribution during SPS. The effects of processing on interface bonding formation and phase evolution were investigated and discussed in detail to provide insight into fundamental phenomena and microstructural evolution in SPSed FexN.
