Abstract

The zirconium-deuterium system in addition to alpha -Zr consists of three deuteride phases: gamma , delta , and epsilon . Each phase exists over a wide range of compositions. The gamma phase is tetragonal. The delta phase is cubic (CaF/sub 2/-type). The epsilon phase is tetragonal. Its lattice constants vary with composition as it approaches stoichiometry of ZrD/sub 2/. The unit cell contains 4ZrD/sub 2/ with atoms in similar positions as in the delta phase. The gamma phase retains its structure over long periods of time at room temperature. The delta + epsilon region has a finite width. The sizes of interstitial octahedral and tetrahedral voids in alpha -Zr are calculated and shown to be larger or smaller, respectively, than those of tetrahedral sites actually occupied by deuterium atoms in the deuterides to permit interstitial solid solution.

Evidence of FCC titanium hydride formation in. beta. titanium alloy: An X-ray diffraction study

Journal Article Shih, D S ; Birnbaum, H K - Scr. Metall.; (United States)

Three types of titanium hydrides have been reported: delta, epsilon and ..gamma.. hydrides. The delta hydride forms in the composition range from TiH/sub 1.5/ to TiH/sub 1.99/ and has a CaF/sub 2/ structure with metal atoms on an fcc lattice and hydrogen atoms randomly occupying tetrahedral interstitial sites. At higher hydrogen concentrations, TiH/sub 2/, the fct (c/a < 1) epsilon hydride phase is formed below 310 K. The c/a ratio decreases with a decreasing temperature and it reaches and maintains a minimum value of 0.943 below 80 K. The fcc to tetragonal, delta ..-->.. epsilon transformation is apparently diffusionless, similarmore »« less

A conjoint XRD-ND analysis of the crystal structures of austenitic and martensitic Ti{sub 0.64}Zr{sub 0.36}Ni hydrides

Journal Article Cuevas, F ; Latroche, M ; Bouree-Vigneron, F ; ... - Journal of Solid State Chemistry

The crystal structures of the hydrides of austenitic and martensitic Ti{sub 0.64}Zr{sub 0.36}Ni alloy have been investigated by conjoint X-ray diffraction (XRD)-neutron diffraction (ND) analysis. Austenitic Ti{sub 0.64}Zr{sub 0.36}Ni alloy with cubic CsCl-type structure preserves its metal sublattice structure after deuteration. It forms a Ti{sub 0.64}Zr{sub 0.36}NiD{sub 1.5} deuteride with D-atoms occupying half of the octahedrally coordinated 3d sites. On the contrary, the monoclinic TiNi-type structure of martensitic Ti{sub 0.64}Zr{sub 0.36}Ni alloy is modified after deuterium absorption. At P{sub D2}=10{sup 3}Pa and T=298K, two deuterides coexist with orthorhombic CrB-type structure for the metal sublattice and compositions Ti{sub 0.64}Zr{sub 0.36}NiD ({beta}-deuteride)more »« less

Directional metal-hydrogen bonding in interstitial hydrides. III. Structural study of ErCo{sub 3}D {sub x} (0{<=}x{<=}4.3)

Journal Article Filinchuk, Y E ; Yvon, K - Journal of Solid State Chemistry

The ErCo{sub 3}-D{sub 2} system has been studied by in situ neutron powder diffraction (NPD) at 60 deg. C and 0-16 bar deuterium pressure. Two deuteride phases were identified, {beta}-ErCo{sub 3}D{sub 1.07-1.38} and {gamma}-ErCo{sub 3}D{sub 3.7-4.3}. They were structurally characterized at the compositions {beta}-ErCo{sub 3}D{sub 1.37} and {gamma}-ErCo{sub 3}D{sub 3.7} by high-resolution neutron and synchrotron powder diffraction. In contrast to the analogous nickel systems RNi{sub 3}-D{sub 2} (R=Er, Ho; see part I, J. Alloys and Compds. 404-406 (2005) 89-94, and part II, J. Alloys and Compds. 2005, in press), their structures preserve the symmetry of the parent alloy (PuNi{sub 3}-type,more »« less

Hydrogen atom distribution and hydrogen induced site depopulation for the La{sub 2-x}Mg{sub x}Ni{sub 7}-H system

Journal Article Guzik, Matylda N., E-mail: Matylda.Guzik@ife.no ; Physics Department, Institute for Energy Technology, P.O. Box 40, NO-2027 Kjeller ; Hauback, Bjorn C ; ... - Journal of Solid State Chemistry

La{sub 2-x}Mg{sub x}Ni{sub 7} and its hydrides/deuterides were investigated by high resolution synchrotron powder X-ray and neutron diffraction. Upon deuteration the single phase sample of the intermetallic compound with the refined composition La{sub 1.63}Mg{sub 0.37}Ni{sub 7} (space group: P6{sub 3}/mmc) expands isotropically, in contrast to the Mg free phase. The hydrogen uptake, {approx}9 D/f.u., is higher than in La{sub 2}Ni{sub 7}D{sub 6.5}. The refined composition accounts for La{sub 1.63}Mg{sub 0.37}Ni{sub 7}D{sub 8.8} (beta-phase). Rietveld refinements using the neutron and synchrotron diffraction data suggest that deuterium atoms occupy 5 different interstitial sites within both AB{sub 2} and AB{sub 5} slabs, eithermore »« less

NEUTRON AND X-RAY DIFFRACTION STUDIES ON NONSTOICHIOMETRIC METAL HYDRIDES

Technical Report Sidhu, S S ; Satya Murthy, N S ; Campos, F P ; ...

A diffraction study using neutrons and x rays was made of metal hydride systems in which the metal-rich regions are emphasized. The composition range used was 2 to 66.5 at.% H/sub 2/ in Hf, Ti, and Zr; and a system consisting of 62 at.% Ti and 38 at.% Zr. The samples studied were in the form of deuterides, Results of the investigation show that the Zr--D system has alpha , gamma , sigma , and epsilon phases as in the H systems. Differences between the Zr--H and Zr-- D systems are discussed. (J.R.D.)
