  摘要：

  摘要 制备了一系列 Gd-Fe-Cu 合金，通过使用扫描电子显微镜-能量色散 X 射线光谱法 (SEM-EDS) 和 X 射线衍射仪测定 Gd-Fe-Cu 体系的 1073 K 等温截面。射线粉末衍射 (XRD) 技术。在 1073 K 下实验确定了 12 个单相区、11 个两相区和 10 个三相区以及两个液体区。 该温度下的相图以形成新的三元化合物 Gd6Fe20.5Cu2 为特征.5 标记为 A 和八种二元化合物，即 Gd2Fe17、GdFe3、GdFe2、GdCu、GdCu2、GdCu5、Gd0.8Cu5.4 和 Hcp (GdCu)。然而，与之前的研究表明化合物 Gd6Fe23 在 1073 K 下稳定不同，我们证明它不是，并且在 1173 K 下变得稳定。 在八种形成的二元化合物中，

  as-quenched Mg 65 Cu 25− x Gd 10 Ag x alloy ribbons exhibit broad diffraction patterns of amorphous phase. A clear T g (glass transition temperature) and supercooled region (about 40 K) were revealed for all Mg 65 Cu 25− x Gd 10 Ag x alloy ribbons. In addition, the single stage crystallization of the Mg 65 Cu 25 Gd 10 alloy was found to change into three stage crystallization when the Ag element was

  摘要 采用熔融纺丝法制备了厚度为0.1 mm的Mg 65 Cu 25− x Gd 10 Ag x ( x = 0-10) 非晶合金薄带。通过差示扫描量热法 (DSC)、具有 EDS 能力的 SEM、X 射线衍射 (XRD) 和 TEM 技术的组合，研究了非晶合金退火过程中的热性能和微观结构发展。XRD 结果表明，所有这些淬火态的 Mg 65 Cu 25- x Gd 10 Ag x 合金薄带都表现出宽的非晶相衍射图。所有 Mg 65 Cu 25- x Gd 10 Ag x 合金带都显示出清晰的 T g （玻璃化转变温度）和过冷区域（约 40 K）。此外，当添加Ag元素时，发现Mg 65 Cu 25 Gd 10 合金的单阶段结晶转变为三阶段结晶。在平行下，Mg 65 Cu 25- x Gd 10 Ag x 合金的玻璃化转变温度随着Ag含量的增加呈现增加的趋势。然而，随着Ag含量的增加，结晶温度T

  Energy dispersive powder X-ray diffraction measurements with diamond anvil high pressure cells at ambient temperature and pressure up to 50 GPa on the LnM compounds GdCu, LaAg, NdAg, NdZn, CeZn and LaZn show systematically high pressure phase transformations from the cP2 (CsCl-type) structure to lower symmetry phases, however, with only minor effects from valence instabilities.

  The phase diagrams of the Gd-Ni-Pb and Gd-Cu-Pb systems were constructed using X-ray phase analysis. Five ternary compounds GdNiPb (TiNiSi structure type, space group Pnma, a=7.2481(9) Angstrom, b=4.5428(6) Angstrom, c=7.7701(9) Angstrom), Gd2Ni2Pb (Mn2AlB2 structure type, space group Cmmm, a=4.0619(9) Angstrom, b=14.107(2) Angstrom, c=3.6942(9) Angstrom), Gd5NiPb3 (Hf5CuSn3 structure type, space group P6(3)/mcm, a=9.094(1) Angstrom, c=6.6427(7) Angstrom), Gd12Ni6Pb (Sm12Ni6In structure type, space group Im3, a=9.770(2) Angstrom) and Gd6Ni2Pb0.5 (Ho6Co2Ga structure type, space group Immm, a=9.487(1) Angstrom, b=9.673(1) Angstrom., c=10.032(1) Angstrom) exist in the Gd-Ni-Pb system at 870 K. Three ternary compounds GdCu4.60Pb0.40 (AuBe5 structure type, space group F (4) over bar 3m, a=7.1288(5) Angstrom), GdCuPb (LiGaGe structure type, space group P6(3)mc, a=4.5859(3) Angstrom, c=7.4169(3) Angstrom) and Gd5CuPb3 (Hf5CuSn3 structure type, space group P6(3)/mcm, a=9.135(3) Angstrom, c=6.658(2) Angstrom) form in the Gd-Cu-Pb system at 870 K.

• Effect of Cu and Zn on the melting and transformation temperatures of Pr and Gd

  Phase equilibria in the R-rich regions of the R-Cu and R-Zn binary systems (R=Pr and Gd) have been investigated by differential thermal analysis, X-ray powder diffractometry, metallographic analysis and quantitative electron probe microanalysis. In these regions, the lowering (DeltaT) of the melting and transformation temperatures of the rare earth metals by addition of copper and zinc resulted in eutectic and catatectic or eutectoidal type reactions. The DeltaT observed in these systems are discussed and compared with those reported in the literature for the binary systems of Pr and Gd with Mg and with the elements from the 9th to the 14th group of the Periodic Table. In order to complete this systematics, a few Pr-rich Pr-Cd alloys have also been prepared and analysed. (C) 2001 Elsevier Science B.V. All rights reserved.

  The magnetization of GdCu induced by hydrogen uptake was measured within the temperature range of 4.2 to 300 K, occurring phase changes were followed by X-ray diffraction measurements at ambient temperature. The prepared GdCu powder of CsCl-type structure readily absorbed hydrogen at ambient temperature, where hydrogen pressure was below 100 kPa. Hydrogenation changed the magnetism of GdCu in a complex manner from an antiferromagnetic-like type to a paramagnetic-like one. The changes in magnetic properties of GdCu by hydrogenation are governed by hydrogen-induced disproportionation. Within the composition range 0 <[H]/[GdCu]< 1, GdCu disproportionated according to 2GdCu+H(2 ->)GdH(2)+GdCu(2). The magnetization was evaluated by the expression chi(total) = (1-x)chi(GdCu) + (x/2)(chi(GdH2) + chi(GdCu)) hydride was not observed. Hydrogenation beyond [H]/[GdCu] > 1 gave rise to the disproportionation of GdCu(2) causing the change in magnetization. (c) 2008 Elsevier B. V. All rights reserved.
