  Temperature driven hydrogen-induced disproportionation of Zr2Cu

  摘要：

  The absorption of hydrogen by Zr2Cu was studied by the aid of the Zr2Cu-H phase diagram elaborated by Kadel and Weiss. It was found that Zr2Cu hydride was formed at ambient temperature after moderate hydrogen absorption. Hydrogen-induced disproportionation of Zr2Cu occurred at temperatures exceeding 550K. The unknown compound of the gamma phase reported by Kadel and Weiss was identified as Zr7Cu10. It was also found that the beta phase consisted of ZrCu and Zr hydride instead of Zr2CuHx,x=1.0-1.4. The disproportionation behavior was found to follow a different mechanism below and above 973 K. Below 973 K the disproportionation was found to proceed by the reaction sequence, Zr2Cu + H-2 -> Zr7Cu10 + ZrHx + H-2(gamma phase) -> Zr14Cu51 + ZrHx + H-2 (delta phase), and above 973K via the sequence, Zr2Cu + H-2 -> ZrCu + ZrHx + H-2(beta Phase) -> Zr7Cu10 + ZrHx + H-2(delta phase). The difference could be explained by the thermodynamic stability of ZrCu intermetallic compounds. (C) 2009 Elsevier B.V. All rights reserved.

  Abstract Hydrogen absorption in the intermetallic compounds Zr 2 TM (TM = Cu, Ag, Au) with MoSi 2 -type structure was characterized by differential scanning calorimetry (DSC) under hydrogen, hydrogen-storage capacity measurement and X-ray diffraction (XRD). The amount of heat for the exothermic peak in DSC due to hydrogen absorption and the maximum hydrogen-storage capacity increased in the order of

  摘要 采用氢差示扫描量热法(DSC)、储氢容量测量和X射线衍射(XRD)表征了具有MoSi 2 型结构的金属间化合物Zr 2 TM (TM = Cu、Ag、Au)中的吸氢。 . DSC 吸氢放热峰的热量和最大储氢能力按Zr 2 Cu > Zr 2 Ag ≫ Zr 2 Au 的顺序增加。XRD表明Zr 2 Cu和Zr 2 Ag可以分解成Cu或Ag和ZrH x ( x ∼ 2)，而Zr 2 Au可以与氢形成固溶体而不分解。基于Zr 2 TM 分解的估计焓变的幅度和/或符号，这些发现得到了很好的解释。

  TbFe2D3.8, TbNi2D2.4, CuZr2 and NiZr2 metallic glasses have been studied to elucidate the structural characteristics by taking advantage of neutron and X-ray diffraction and using the reverse Monte Carlo (RMC) modeling based on the diffraction data. Topologically, about 98% of D atoms occupy tetrahedral sites formed by metal atoms for TbFe2D3.8 and TbNi2D2.4 metallic glasses. The Volonoi analysis of the structure of CuZr2 and NiZr2 metallic glasses was carried out to elucidate the relationship between the stability of glassy state and the atomic configuration. The prismatic-like polyhedra dominate in NiZr2 metallic glass. In contrast, the icosahedron-like polyhedra faces are preferred for constructing the structure of CuZr2 metallic glass.

  Cu100-xZrx (x = 50, 54, 60 and 66.6) polycrystalline alloys were prepared by arc-melting. The crystal structure of the ingots has been examined by X-ray diffraction. Non-equilibrium martensitic phases with monoclinic structure were detected in all the alloys except Cu33.4Zr66.6. Temperature dependencies of electrical resistivity in the temperature range of T = 4-300 K have been experimentally obtained as well as room temperature values of Hall coefficients and thermal conductivity. Electrical resistivity demonstrates anomalous behavior. At the temperatures lower than 20 K, their temperature dependencies are non-monotonous with pronounced minima. At elevated temperatures they have sufficiently non-linear character which cannot be described within framework of the standard Bloch-Gruneisen model. We show that experimental resistivity dependencies may be perfectly fitted by generalized Bloch-Gruneisen model with variable Debye temperature. We found that both the electrical resistivity and the Hall coefficients reveal metallic-type conductivity in the Cu-Zr alloys. The estimated values of both the charge carrier mobility and the phonon contribution to thermal and electric conductivity indicate the strong lattice defects and structure disorder.
