  • Liu Y.; Mazumder J.; Robertson B.W.; Tewari S. (Taylor & Francis Group, 1996-03-01)
    The dislocation structure, the dislocation dissociation and the Burgers vectors in laser clad NbAl3 on a Nb substrate were investigated by transmission electron microscopy including weak beam contrast analysis by the g.b ...
  • Möller H.-J. (Taylor & Francis Group, 1981-04-01)
    The application of the Coincidence site lattice (CSL) model to the diamond cubic structure allows a purely geometric modelling of specific grain boundaries. Symmetric ⟨011⟩ CSL tilt boundaries with [Sgrave] ≤ 33 were ...
  • Yang Y.S.; Wu S.K. (Taylor & Francis Group, 1992-01-01)
    Transmission electron microscopic study on a α2 + γ two-phases Ti-40 at.% Al alloy demonstrates that (011)γ/(101)γ twin does occur in TiAl. Differently-orientated γ regions are observed to coexist within the same γ lamella ...
  • Watanabe K.; Hiratsuka K.; Yamaguchi H. (Taylor & Francis Group, 1991-07-01)
    Using a 300 kV transmission electron microscope, we present experimental (100) lattice images of GaAs and ZnSe, which allow the resolution and identification of sublattices. A detailed comparison between the experimental ...
  • Caron P.; Khan T.; Veyssière P. (Taylor & Francis Group, 1989-08-01)
    Ni–23.7at.%A1–0.3at.%Hf single crystals were deformed by creep at 760°C along [001]. A weak-beam electron microscopy study of superdislocations revealed that the primary slip plane is {110} and that superdislocation motion ...
  • Midgley P.A.; Vincent R.; Cherns D. (Taylor & Francis Group, 1992-08-01)
    Large-angle convergent-beam electron diffraction (LACBED) has been used in conjunction with dark-field imaging to determine the nature of {110} twinning in YBa2Cu3O7-x (YBCO). The orthorhombic ratio (b-a)/a has been shown ...
  • Mitchell T.E.; Castro R.G.; Chadwick M.M. (Taylor & Francis Group, 1992-06-01)
    Plasma-sprayed tetragonal MoSi2 has been examined by transmission electron microscopy. Growth twins are commonly observed in the microstructure. Analysis of diffraction patterns using a stereographic projection indicates ...
  • Numakura H.; Minonishi Y.; Koiwa M. (Taylor & Francis Group, 1991-05-01)
    Electron microscopy observations were made on Zr polycrystals deformed at room temperature. Deformation substructure consists of ⅓⟨1120⟩ dislocations mostly in screw orientations, ⅓⟨1123⟩ dislocations on {1011} planes, and ...
  • Salisbury I.G.; Loretto M.H. (Taylor & Francis Group, 1979-03-01)
    Specimens of silicon have been irradiated at 1 MV, at temperatures between 300° and 650°C in a high-voltage electron microscope. Observations made during irradiation, taken together with more detailed analyses carried out ...
  • Schober T.; Trinkaus H. (Taylor & Francis Group, 1992-05-01)
    Ti-tritides containing about 10% (H/M) tritium were aged at 300 and 550[ddot]C for several weeks and then inspected for 3He bubble formation by transmission electron microscopy. Micrographs of α-phase regions aged at ...
  • Zhu JaneG.; Carter C.Barry (Taylor & Francis Group, 1990-09-01)
    The geometry of 60° dislocations at the (001) GaAs/Si. heterojunction is discussed considering transmission electron microscopy images of plan-view samples. The GaAs examined was grown by molecular beam epitaxy on to a Si ...
  • Narayan J. (Taylor & Francis Group, 1978-04-01)
    Dislocations of a⟨100⟩ Burgers vector lying in {100} planes have been observed in magnesium oxide using transmission electron microscopy. The evidence for climb of these dislocations is presented.
  • Miyano T.; Iwanishi M.; Harada T.; Kaito C.; Shiojiri M. (Taylor & Francis Group, 1983-01-01)
    Abstract Rutile crystals, grown in vacuum-deposited amorphous films by electron beam heating, have been investigated by high-resolution transmission electron micro scopy with the aid of computer image simulation. A new ...
  • Mackrodt W.C.; Harrison N.M.; Saunders V.R.; Allan N.L.; Towler M.D.; Aprà E.; Dovesi R. (Taylor & Francis Group, 1993-10-01)
    Ab initio Hartree-Fock calculations are reported of the electronic structures of CaO, VO, MnO and NiO. They are found to be essentially ionic in nature with ground states that are insulating, and, in the case of VO, MnO ...
  • Bollmann W. (Taylor & Francis Group, 1981-11-01)
    In polycrystalline materials, grain (or phase) boundaries usually meet as triplets, joined in a respective line, the ‘triple line’. Single boundaries can be represented as dislocation networks. At the triple line the ...
  • Schulson E.M.; Lim P.N.; Lee R.W. (Taylor & Francis Group, 1984-09-01)
    Experiments have revealed a brittle to less-brittle transition in polycrystalline ice Ih slowly strained (10−6 s1) under uniaxial tension at temperatures from −20°C to −5°C. The transition occurs at a ‘critical grain size’ ...
  • Calleja J.M.; Vogt H.; Cardona M. (Taylor & Francis Group, 1982-02-01)
    The Raman scattering efficiencies for Г phonons have been measured for Gap, ZnTe, ZnSe, ZnS, CAF2, SrF2and BAF2, using the Brillouin-Raman method. The results are used to calibrate resonance Raman curves previously published ...
  • Briscoe B.J.; Mahgerefteh H. (Taylor & Francis Group, 1986-05-01)
    The absorption of N2, He and two of their mixtures in PTFE are studied up to a maximum pressure of 51 MPa and a temperature range of 0–70°C using a vibrating-reed technique. The data indicate that relatively large amounts ...

    Computer simulation techniques have been used to calculate the energy and entropy changes, at constant volume, for the formation of a Frenkel defect, for the association of a cation vacancy with a cation impurity, and for ...
