Interaction in (Ti,Sc)Fe2–H2 and (Zr,Sc)Fe2–H2 systems
摘要:
Results of investigation of hydrogen sorption properties of Ti(Zr)(x)Sc(1-x)Fe(2)(x= 1, 0.8 and 0.5) alloys are presented. The measurements were performed for pressures up to 3000 atm. In case of titanium alloys hydride formation was established only for x = 0.5. Estimated equilibrium absorption pressure for x = 0.8 and 1.0 was too high for experimental limits of the device. In case of zirconium alloys hydride formation was found for all three concentrations. Absorption-desorption isotherms were measured for the first time for ZrFe(2)-H(2) system. Calculated enthalpy of hydrogen desorption was found to be 21.3 kJ/mole H(2). (C) 2007 Elsevier B.V. All rights reserved.

Ni-substituted Zr3Fe alloys with 30 and 50 at.% Ni were synthesized and their hydrogen absorption/desorption characteristics were compared experimentally (pressure–composition isotherms, thermal desorption spectroscopy, in-situ neutron diffraction) and by computational methods (ab-initio molecular dynamics (AMD), nudged elastic band theory (NEB)). All the alloys absorbed hydrogen to a hydrogen-to-metal

Abstract Investigations of the solidsolutions in Zr–Zn–Fe, Co, Ni} ternarysystems at 600 °C are presented. Crystal structures of the solidsolutions based on the binary compounds ZrNi 5 , Zr 7 Ni 10 , ZrNi, Zr 2 Ni, ZrCo, Zr 2 Co, ZrFe 2 , ZrZn 2 and Zr 2 Zn were investigated by X-ray powder diffraction.

Abstract The conditions for the realization of the hydrogenation–disproportionation–desorption–recombination (HDDR) process in intermetallic compounds (IMC) ZrT 2 (T=Cr, Mn, Fe, Co) have been determined by means of differential thermal analysis (DTA) and X-ray phase analysis (XPhA). It was determined that after HD, the C14 type Laves phase ZrCr 2 decomposes into a zirconium hydride and chromium. After

Lavas phase compounds (Yx Zr 1-x )Fe 2 have C15 structure, and are ferromagnetic. They absorb hydrogen under the condition of 1 atm, room temperature, to form hydrides (Yx Zr 1-x )Fe 2 H y . Hydrogen content y increases from O(ZrFe 2 ) to 4.2(YFe 2 ) with x continuously. The dependence of µ Fe and T c of hydrides on x is different for hydrogen content, namely y >3 or y <3. In \(y\gtrsim}3\), the hydrogen
熔岩相化合物 (Y x Zr 1- x )Fe 2 具有 C15 结构,并且具有铁磁性。它们在 1 个大气压的室温条件下吸收氢,形成氢化物 (Y x Zr 1- x )Fe 2 H y 。氢含量 y 随 x 从 O(ZrFe 2 ) 增加到 4.2(YFe 2 )。氢化物的 μ Fe 和 T c 对 x 的依赖性对于氢含量是不同的,即 y >3 或 y <3。在\(y\gtrsim}3\)中,假设氢与母体化合物形成尖晶石结构,并且氢处于类H状态。在\(y\lesssim}3\)中,假设氢以类似H + 的状态形成固溶体。
Abstract The structure of ZrFe2 and ZrCo2 deuterides prepared under very high deuterium pressure has been studied by neutrondiffraction (ND) at 10 K. The patterns of both compounds are refined with a mixture of intermetallic compound and deuteride. For ZrFe2Dx, the cell volume increases with 23% and the 2.7 D/f.u. are located randomly in A2B2 sites. The Fe moments order in a ferromagnetic structure
