摘要：

Sm2Fe17 alloys prepared by strip casting technique can be directly nitrided to prepare interstitial Sm2Fe17NX compounds without pre-crushing. A phenomenon of spontaneous pulverization in the Sm2Fe17 strips induced by nitrogenation is found. This kind of pulverization may arise from the inter-granular fracture along the Sm-rich grain boundary phase as well as trans-granular fracture of Sm2Fe17 primary phase. Anisotropic Sm2Fe17N2.85 powders with a remanence (B-r) of 14.1 kGs, a coercive force (H-i(c)) of 12.1 kOe, and a maximum energy product ((BH)(max)) of 33 MGOe can be prepared using the nitrided strips.
