Sm2Fe17 nitrided powder was consolidated into bulk material at room temperature in an ambient atmosphere by the compression shearing method. The resultant bulk material retained the original Sm2Fe17N3 phase structure without any appreciable decomposition of the Sm2Fe17N3 phase. The bulk material had a density equivalent to 92.7% of the X-ray density of the Sm2Fe17N3 phase. The bulk materials produced at 473 K in nitrogen atmosphere by the compression shearing method had virtually the same density as that produced at room temperature in an ambient atmosphere, but exhibited a maximum energy product of 65.7 kJm−3 with a coercivity of 892 kAm−1.
