摘要：

A samarium-iron nitride Sm2Fe17N3 powder was shock-consolidated by using a propellant gun with metal-plate impactor system. Disk-like magnets were consolidated under each experimental condition. At an optimum condition in this study, apparent density of shock-compacted Sm2Fe17Nx magnets was 97% of solid density, and X-ray diffraction patterns of these magnets showed no appearance of the decomposition of rhombohedral Sm2Fe17Nx structure. The highest value of the maximum energy product obtained so far was 10.5 MG.Oe. Microstructural analyses suggested the possibility of improving magnetic properties of the magnets.
