Effect of the Nb Content on the Microstrcuture of Sm2Fe17 Alloy

摘要:

通过氢化-歧化-脱氢-重组法制备Sm2(Fe，M)17(M=Nb)合金，探讨了添加合金元素Nb对Sm2Fe17合金的微结构的影响。通过扫描电子显微镜和能谱仪、X射线衍射仪等分析手段对Sm2(Fe，M)17(M=Nb)进行测试和分析表明：添加微量的Nb元素可以有效的改善Sm-Fe合金铸态组织的显微结构。

Abstract:

Sm2(Fe,M)17 (M=Nb) alloy is prepared through HDDR (Hydrogen-Disproportionation-Desorption-Recombination) method. Influence of Nb element addition on the microstrcuture of Sm2Fe17 alloy was studied. The results show that the as-cast structure of Sm2(Fe,M)17(M=Nb) alloy can be improved effectively.
