  摘要：

  摘要 本文详细研究了 Ga 含量为 15-45 at.% 的 Fe-Ga 合金的显微组织和相组成，在低于 600 °C 的温度下进行长时间退火处理。本研究使用了 X 射线衍射 (XRD)、透射电子显微镜 (TEM)、振动样品磁强计 (VSM) 和电子背散射衍射 (EBSD) 结合扫描电子显微镜 (SEM) 方法。结果与 W. Koster 等人提出的四种现有 Fe-Ga 相图的预测进行了比较。(1977), J. Bras 等。(1977)、O. Kubaschewski (1982) 和 H. Okamoto (1993)。发现了几个重要的不一致，需要修正三个平衡边界的位置。低于 400 °C，一个不完整的，如果有的话，退火 300 小时后，可以看到从亚稳态（A2 或 D03）到平衡（L12）状态的转变。在 450-500 °C 下退火 300 小时的 25.5-28.1% Ga 合金仅表现出平衡

  The isothermal section of the Nd-Fe-Ga ternary system at 773 K was constructed using X-ray diffraction analysis. Ten binary compounds, Nd2Fe17, Nd5Fe17, Nd9Ga4, Nd5Ga3, NdGa, NdGa2, FeGa3, Fe3Ga4, alpha-Fe6Ga5 and alpha-Fe3Ga, and three ternary compounds, NdFe2Ga8, NdFe5Ga7 and Nd6Fe13Ga were existed in this isothermal section. The solid solutions Nd2Fe17.00-15.57Ga0-1.43 (Th2Zn17-type structure, space group R (3) over barm, NdFe5.46-4.65Ga6.(54-7.35) (ThMn12-type structure, space group 14/mmm) and Nd6Fe13.0-12.Ga-0(1.0-2.0) (La6Co11Ga3-type structure, space group 14/mcm) were formed by substitution of Ga for Fe in the compounds Nd2Fe17, NdFe5Ga7 and Nd6Fe13Ga at 773 K, respectively. The ternary compound NdFe2Ga8 is CaCo2Al8-type (space group Pbam) with a = 1.43742 (4), b = 1.24601 (4), c = 0.40479 (1)). The homogeneity range of NdGa2 is from 66.7 to 74.7 at.% Gain Nd-Ga side but the solid solubility of Fe in this compound is very small. The homogeneity ranges of Nd6Fe13Ga and NdFe5Ga7 are from 5.0 to 10.0 and from 50.3 to 56.5 at.% Ga, respectively. The maximum solid solubilities of Ga in Nd2Fe17 is 7.5. The homogeneity ranges for the other compounds are small. (C) 2009 Elsevier B.V. All rights reserved.

  The isothermal section (500 degrees C) of the phase diagram of the Gd-Fe-Ga ternary system was investigated by X-ray powder diffraction analysis. Eleven binary compounds, GdGa2, GdGa, Gd3Ga2, Gd5Ga3, GdFe2, GdFe3, Gd2Fe17, Fe3Ga, Fe6Ga5, Fe3Ga4 and FeGa3, have been confirmed. Two ternary compounds, GdFe5.3Ga6.7 and GdFe5Ga7, were found in this ternary system at 500 degrees C. The compound GdFe5.3Ga6.7 is orthorhombic ScFe6Ga6-type structure (space group Immm) with a = 0.8567 (9), b = 0.86960 (9) and c = 0.50782 (5) nm, while the compound GdFe5Ga7 is tetragonal ThMn12-type structure (space group 14/mmm) with a = 0.8651(1) and c = 0.50934 (6) nm. The isothermal section at 500 degrees C consists of 16 single-phase regions, 31 two-phase regions and 16 three-phase regions. The maximum solid solubilities of Ga in GdFe2, GdFe3, Gd2Fe17 are 9.2, 9.0, and 44.3 at.% respectively The homogeneity range of GdGa2 is from 22 to 33.3 at.% Ga in Gd-Ga side but the solid solubility of Fe in this compound is very small. The homogeneity range of GdFe5Ga7 is from 53.8 to 59.2 at.% Ga. Very limited solid solutions were measured in the other compounds. (c) 2008 Elsevier B.V. All rights reserved.
