高エネルギーXAFSによる硬質磁性材料Sm Fe Nの研究
Webb5 okt. 2024 · The synthesized Sm 2 Fe 17 N 3 powder surely has a higher coercivity temperature tolerance than Nd-Fe-B sintered magnets in environments around 473 K. Considering the fact that Sm 2 Fe 17 N 3 has a huge anisotropy field of up to 260 kOe, possibilities for further improvement should remain. Webb4 juni 2024 · Abstract. Sm2Fe17N3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sm is bonded in a trigonal planar geometry to four Fe and three equivalent N atoms. There are one shorter (3.11 Å) and three longer (3.33 Å) Sm–Fe bond lengths. All Sm–N bond lengths are 2.51 Å. There are four inequivalent Fe sites. destination b2 shopee

WebbSm2Fe17N3, alloy (SFN) is a well known magnet powder expected to be useful for a bonded magnet[1]. Besides the magnetization is as high as that of Nd2Fe14B alloy, both the uni-axial anisotropy and the Curie temperature are higher than those of it. As a result, it is possible to obtain high coercivity after just milling the alloy and also possible to obtain … Webb30 nov. 2016 · Sm 2 Fe 17 N 3 alloy is well known as a high-performance permanent magnet which has not only high magnetization equivalent to Nd 2 Fe 14 B alloy but also … WebbThus, high performance anisotropic polymer-bonded magnets with Sm2Fe17N3 powder and isotropic polymer-bonded magnets with SmFe9Nx powder have been commercialized by magnet manufacturers in Japan and China. Here, we will introduce present situation and future prospect of the Sm-Fe-N magnet. 版 型: A4 PDFファイルサイズ: 1,291Kバイト destination b2 fahasa
