合金元素对Sm₂（Fe,M）₁₇N_y磁性的影响

摘要: 采用机械破碎与氢破碎和氮气-固相反应法制得了Sm₂(Fe,M)₁₇N_y化合物粉末及粉末压结体,研究了金属钐含量、过渡元素(M=Co、Cr、V、Mn、Zr、Si、Ga)部分取代铁时对Sm₂(Fe_1-xM_x)₁₇N_y粉末压结体磁性能的影响。结果表明:铬、镓能显著提高粉末的矫顽力。Sm₂(Fe_0.017Ga_0.983)₁₇N_y粉末压结体的矫顽力达到iHc=2000kA/m。

Abstract: Sm₂(Fe,M)₁₇N_y compound powder has been made by the hydrogen treatment and nitrogen absorption treatment. The effects of Sm content and the additions of Co,Cr,V,Zr,Si and Ga on magnetic properties of Sm₂(Fe_1-xM_x)₁₇N_y, compound powder have been studied.The coercivity of Sm₂(Fe_0.987Ga_0.017)₁₇N_y powder is 2 000kA/m
