(Taylor & Francis Group, 1993-05-01){103}⟨331⟩ slip is found to be activated in MoSi2 single crystals by deformation along [001] in uniaxial compression at 1000°C. The {103} slip plane has been determined by slip trace analysis. Observations by transmission ...
-
(Taylor & Francis Group, 1995-05-01)High-resolution transmission electron micrographs of {1101} interfacial twin dislocations in Ti thin films, previously published in this journal, are re-examined. Computer simulations of the experimental images have been ...
-
(Taylor & Francis Group, 1989-06-01)The possibility for superdislocations in L12-ordered alloys to cross-slip from (111) to (111) planes has been considered. The stress to induce homogeneously this cross-slip is very high. Cross-slip can be locally activated, ...
-
(Taylor & Francis Group, 1988-12-01)In situexperiments are performed in Ni3AL at room temperature. We observe reversible changes of antiphase boundary (APB) planes between {111} and {100}, and movements in {111} planes controlled by the crossing of sessile ...
-
(Taylor & Francis Group, 1994-12-01)Abnormal growth and relaxation of a GaSb film on GaAs(001) is studied by transmission electron microscopy. Irregularly shaped and abnormally large GaSb islands are relaxed by 60° misfit dislocations. Having the same sign. ...
-
(Taylor & Francis Group, 1992-08-01)Local-density-functional theory is used to determine the structure of molecular water along the c channel in α-quartz. We use a 105-atom cluster terminated by H atoms and find that water has a large effect on the silicate ...
-
(Taylor & Francis Group, 1992-06-01)A local-density-functional cluster method is used to calculate the structure and vibrational modes of C60. We find C–C lengths in good agreement with observed values. The effect of doping the molecule with three extra ...
-
(Taylor & Francis Group, 1995-12-01)The temperature dependence of ⟨111⟩ tilt grain boundaries with angles of misorientation of 38·2° and 40·5° was investigated in bicrystals of both pure (99·999%) Al and the same Al doped with 10ppmGa in the temperature ...
-
(Taylor & Francis Group, 1991-11-01)The technique of reflection electron microscopy (REM) has been combined with wedge transmission electron microscopy (WTEM) in a single instrument using a single wedge-shaped specimen. This combination needs only a commercial ...
-
(Taylor & Francis Group, 1992-09-01)The theoretical modelling of the temperature-dependent metastable dangling-bond density in undoped hydrogenated amorphous silicon (a-Si: H) is critically reviewed. It is shown that thermal broadening of the band tails ...
-
(Taylor & Francis Group, 1988-08-01)Self-diffusion data for V exhibit a nonlinear Arrhenius behaviour which is usually attributed to the coexistence of two or more diffusion mechanisms. In this Letter we draw attention to the fact that the nonlinearity ...
-
(Taylor & Francis Group, 1994-02-01)Kelvin's conjecture, that a b.c.c. arrangement of his minimal tetrakaidecahedron divides space into equal cells of minimum surface area, has stood for over one hundred years. We have found a counter-example, in the form ...
-
(Taylor & Francis Group, 1996-01-01)A general criterion for the selection of the nearest-neighbour relation between two joining crystals is proposed. It has been applied to the study of the dislocation balance at a Σ=3-Σ=3-Σ=9 triple junction in high-purity nickel.
-
(Taylor & Francis Group, 1994-11-01)The normal grain growth of materials such as metals, ceramics or even biomembranes is reconsidered, based on the formalism obtained by Louat and improved by Mulheran and Harding. A critical discussion of the model is ...
-
(Taylor & Francis Group, 1995-07-01)The construction of the γ surface requires the application of mechanical constraints in order that the energy of non-equilibrium fault configurations can be calculated. The choice of mechanical constraints is not unique ...
-
(Taylor & Francis Group, 1995-05-01)A method for calculating the activation energy spectrum from isothermal data using Fourier techniques is used for studying the deformation processes in amorphous metals. The influence of experimental error on the calculated ...
-
(Taylor & Francis Group, 1992-12-01)The tracer diffusivity of Co in amorphous NixZr1-x has been measured as a function of pressure for 0·42≤x≤0·62. The primary conclusions that can be drawn from the results of these measurements is that the activation volume ...
-
(Taylor & Francis Group, 1995-12-01)A new vertex-based model of two-dimensional grain growth is presented. The motion of each vertex is determined by the curvature-driven motions of the adjacent boundaries. Boundary curvatures are approximated by a geometrical ...
-
(Taylor & Francis Group, 1987-02-01)Anomalous small-angle X-ray scattering (ASAXS) spectra have been recorded for an unmixed Cu(0·426)Ni(0·422)Fe(0·152) alloy. The data were obtained at different photon energies near the Fe and Ni absorption edges: ASAXS ...
-
(Taylor & Francis Group, 1988-07-01)Relative spectroscopic measurements of the bulk modulus of GaIn As P lattice-matched to InP yield a value within 1% of that of InP. This surprising result is not in agreement with accepted interpolated values but is predicted ...
