采用扫描电镜、俄歇探针、Ｘ射线衍射、热磁分析、热磁分析等方法深入研究了Ｎｌ（３４）Ｆｅ（６０）Ｏ６合金的显微组织。发现合全的平衡组织由Ｎｄ２Ｆｅ（１７）主相、含氧的富钕相和一个Ｎｄ－Ｆｅ－Ｏ三元铁磁性用（记为Ｔ１相）组成，该相在８４０℃通过Ｎｄ２Ｆｅ（１７）相与富Ｎｄ液相的包晶反应形成，它的成分约为Ｎｄ（３４）Ｆｅ（５０）Ｏ（１０），居里温度为１８０℃．其Ｘ射线衍射峰可用点阵常数ａ＝０．７７１ｎｍ、ｃ＝２．２２８ｎｍ的四方晶胞标定，该相很可能是Ｎｄ－Ｆｅ二元系中的亚稳相（Ａ１）含氧后转变而成的稳定相。
The microstructure of Nl (34) Fe (60) O6 alloy was investigated by scanning electron microscopy, Auger probe, X-ray diffraction, thermal analysis and thermal analysis. It was found that the perfect balance of the microstructure consists of the main phase of Nd2Fe (17), the neodymium-rich neodymium phase and a Nd-Fe-O ternary ferromagnetism (denoted T1 phase) passing through Nd2Fe (17) The phase is formed by peritectic reaction with the Nd-rich liquid phase. The composition of the phase is Nd (34) Fe (50) O (10) and the Curie temperature is 180 ℃. The X-ray diffraction peaks can be calibrated with tetragonal cells with a lattice constant of a = 0.771nm and c = 2.228nm. This phase is probably the metastable phase in the Nd-Fe binary system (A1) Into the stable phase.
