  673 K 时 La-Ni-Si 系统中的相关系

  摘要：

  摘要 通过 X 射线衍射 (XRD)、差热分析 (DTA)、扫描电子显微镜 (SEM) 和电子探针微量分析 (EPMA) 研究了 673 K 下 La-Ni-Si 三元体系中的相关系。所有的相关系都是在 673 K 下研究的。在这个温度下，已经确认了 14 种三元化合物的存在。该部分由35个单相区、78个二相区和47个三相区组成。在 673 K 时，Si 在 Ni、La 2 Ni 7 、LaNi 5 和 La 2 NiSi 中的最大固溶度分别约为 9、3、8.33 和 5 at.%。几种三元化合物形成一个均质区，可以表示为 LaNi 11.6–9.5 Si 1.4–3.5 、LaNi 8.8–8.4 Si 4.2–4.6 和 LaNi 7.8–6.5 Si 5.2–6.5 。

  the quaternary alloy La7Sm3Mg80Ni10, and the structural evolutions during hydrogen sorption and desorption were investigated and described. According to the findings, ball milling lowers the size of grains and particles while also altering their surface properties. The as-cast alloy absorbs 4 wt% H2 in 118, 67, and 58 s at 473, 533, and 553 K, respectively, whereas the as-milled alloy takes 108, 56

  在本文中，采用铸造和球磨工艺制造四元合金 La 7 Sm 3 Mg 80 Ni 10，并研究和描述了氢吸附和解吸过程中的结构演变。根据研究结果，球磨降低了晶粒和颗粒的尺寸，同时也改变了它们的表面特性。铸态合金在 473、533 和 553 K 时分别在 118、67 和 58 秒内吸收了 4 wt% H 2 ，而铣态合金则需要 108、56 和 50 秒。此外，铸态和铣削态合金的首次放氢温度分别为 553.9 和 547.4 K。研磨态和铸造态合金的脱氢焓变绝对值（ΔH ) 为 77.13 和 76.52 kJ/mol，表观脱氢活化能 ( E de ) 分别为 80.79 和 78.72 kJ/mol。

  The isothermal section of the phase diagram of the ternary system La-Ni-Cu has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy and electron microscopy techniques. It consists of 13 single-phase regions, 23 two-phase regions and 11 three-phase regions. At 673 K, the maximum solid solubility of Cu in La2Ni7, LaNi3, La7Ni16, LaNi3 and LaNi is about 2, 2, 3, 3 and 5 at.% Cu, respectively. The solid solubility of Cu in La7Ni3 and Ni in LaCu6 is too small to observe. Cu and Ni can replace each other in LaNi5 and LaCu5, the LaNi5 and LaCu5 form a continuous solid solution. The maximum solid solubility of Ni in LaCu2 and LaCu is about 15 and 4at.% Ni, respectively. A new ternary compound La10Cu85Ni5 has been observed in the La-Ni-Cu ternary system.

  The isothermal section of the phase diagram of the ternary system La-Ni-Nb at 673 K has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy, and electron microscopy techniques. It consists of 14 single-phase regions, 25 two-phase regions, and 12 three-phases regions. At 673 K, the maximum solid solubilities of Nb in Ni, LaNi5, LaNi7, LaNi3, La7Ni16, and LaNi3 is about 3, 5, 2, 3, 3, and 2 at.% Nb, respectively. The composition range of the Nb in NbNi3 is about from 23.5 to 27 at.% Nb. No ternary compounds were observed. (C) 2004 Elsevier B.V. All rights reserved.

  The phase relationships in the La-Ni-Sn ternary system at 673 K have been investigated by means of X-ray powder diffraction (XRD), differential thermal analysis (DTA), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). Most of this ternary system was studied at 673 K. At this temperature, a new ternary compound whose atomic ratio is close to La/Ni/Sn = 1:1:3 has been found. The existences of 15 binary compounds La7Ni3, LaNi, La2Ni3, La7Ni16, LaNi3, La2Ni7, LaNi5, Ni3Sn, Ni3Sn2, Ni3Sn4, La5Sn3, La5Sn4, LaSn, La3Sn5, LaSn3 and seven other ternary compounds LaNi5Sn, LaNi4Sn2, LaNi2Sn2, La3Ni2Sn6, La3Ni2Sn7, La3Ni8Sn16, LaNiSn have been confirmed too. There are 31 three-phase regions in the 673 K isothermal section. Due to the lower melting point of Sn (about 504 K), a small part of the ternary system that lies in the Sn-rich part was studied at 483 K. (C) 2003 Elsevier B.V. All rights reserved.
