Abstract
The spark plasma sintering (SPS) method can consolidate powders at low temperatures over a short period. The addition of dynamic compression (DC) can produce bulk materials at lower temperatures. To demonstrate the effect, the study used SPS-DC to consolidate Sm2Fe17N3 powder, which decomposes into α−Fe and SmN phases above 873 K. The SPS-DC method was able to consolidate Sm2Fe17N3 powder into bulk material at 473 K. The Sm2Fe17N3 magnet produced at 473 K by the SPS-DC method showed a relative density of 88 %, comparable to that of the Sm2Fe17N3 magnet produced at 673 K by the conventional SPS method. The Sm2Fe17N3 bulk Sm2Fe17N3 magnet produced at 473 K by the SPS-DC method exhibited a high coercivity of 9.45 kOe.
