    The ramification of micropipes is observed using scanning electron microscopy, optical microscopy, and synchrotron x-ray radiography. The conditions for the ramification of dislocated micropipes are determined theoretically within a model when the angles between dislocation lines are small. It is shown that the ramification of micropipes into two smaller ones is possible only for micropipes with radii that exceed the equilibrium micropipe radius and is associated with a decrease in the total micropipe surface area. © 2002 American Institute of Physics.

    Abstract A theoretical model for the description of the experimentally observed ([1] M.F. Chisholm, D.A. Smith, Philos. Mag. A 59 (2) 181 (1989)) formation of split dislocations in low-angle tilt boundaries in oxide superconductors is suggested. Conditions under which the splitting of dislocations in low-angle [100] tilt boundaries is energetically favorable are determined theoretically.

    Abstract A solution of the boundary-value problem in the gradient theory of elasticity concerning a rectilinear edge dislocation parallel to the interface between phases with different elastic moduli and gradient coefficients is obtained. The interaction between the dislocation and the interface is considered on a nanoscopic level. It is shown that the stress field has no singularities on the dislocation line and remains continuous at the interface, unlike the classical solution, which is singular at the dislocation line and allows a discontinuity of two stress components at the interface. The gradient solution also removes the classical singularity of the image force for the dislocation on the interface. An additional elastic image force associated with the difference in the gradient coefficients of contacting phases is also determined. It is found that this force, which has a short range and a maximum at the interface, expels the edge dislocation into the material with a smaller gradient coefficient.

    Abstract The results of application of gradient theory of elasticity to a description of elastic fields and dislocation and disclination energies are considered. The main achievement made in this approach is the removal of the classical singularities at defect lines and the possibility of describing short-range interactions between them on a nanoscopic level. Non-singular solutions for stress and strain fields of straight disclination dipoles in an infinite isotropic medium have been obtained within a version of the gradient theory of elasticity. A description is given of elastic fields near disclination lines and of specific features in the short-range interactions between disclinations, whose study is impossible to make in terms of the classical linear theory of elasticity. The strains and stresses at disclination lines are shown to depend strongly on the dipole arm d. For short-range interaction between disclinations, where d varies from zero to a few atomic spacings, these quantities vary monotonically for wedge disclinations and nonmonotonically in the case of twist disclinations, and tend uniformly to zero as disclinations annihilate. At distances from disclination lines above a few atomic spacings, the gradient and classical solutions coincide. As in the classical theory of elasticity, the gradient solution for the wedge-disclination dipole transforms to the well-known gradient solution for a wedge dislocation at distances d substantially smaller than the interatomic spacing.

    Abstract The energy characteristics of orthogonal rows of partial misfit dislocations with V-shaped stacking faults in thin-film heteroepitaxial systems are analyzed theoretically. It is shown that they should appear only in very thin epitaxial films of nanoscopic thickness and for high values of the mismatch exceeding a definite value. Under these conditions partial misfit dislocations associated with V-shaped stacking faults are typical elements of the defect structure of nanolayer heterosystems. For smaller mismatches and larger films thicknesses total misfit dislocations should form.

    Abstract The solution of the boundary-value problem on a rectilinear screw dislocation parallel to the interface between phases with different elastic moduli and gradient coefficients is obtained in one of the versions of the gradient theory of elasticity. The stress field of the dislocation and the force of its interaction with the interface (image force) are presented in integral form. Peculiarities of the short-range interaction between the dislocation and the interface are described, which is impossible in the classical linear theory of elasticity. It is shown that neither component of the stress field has singularities on the dislocation line and remains continuous at the interface in contrast to the classical solution, which has a singularity on the dislocation line and permits a discontinuity of one of the stress components at the interface. This results in the removal of the classical singularity of the image force for the dislocation at the interface. An additional elastic image force associated with the difference in the gradient coefficients of contacting phases is also determined. It is found that this force, which has a short range and a maximum value at the interface, expels a screw dislocation into the material with a larger gradient coefficient. At the same time, new gradient solutions for the stress field and the image force coincide with the classical solutions at distances from the dislocation line and the interface, which exceed several atomic spacings.

    Abstract We report a new effect, observed experimentally in silicon under irradiation with visible-range light with a power density of 0.2–1.5 W/cm2 for 8 s. The effect consists in an increase of microhardness on the side opposite to the irradiated side and is not purely thermal in character. After irradiation, the changes decrease exponentially with time with an activation energy of 0.75±0.05 eV, a value which is characteristic for the migration and reorientation of one of the types of intrinsic interstitial atoms. A qualitative explanation is given for the effect on the basis of a model previously proposed for the case of long-range influence of ion irradiation.

    Notes:
    Abstract A model is developed for describing phason defects in quasicrystals in the form of dilation filaments. This model is used to calculate the energy of edge dislocations in quasicrystals including the interaction of this type of dislocation with its “intrinsic” phason defects and with the equilibrium phason defects present in a quasicrystal. It is shown that the contribution of “intrinsic” phason defects to the total energy of an edge dislocation in a quasicrystal is substantial.

    Notes:
    Abstract The elastically strained state of the interface in directly-bonded silicon structures has been studied by x-ray diffraction topography and IR spectrometry. The pattern of the contrast observed in the x-ray topographs and the intensity oscillations in the IR spectra indicate a periodic strain distribution caused by the long-period surface microroughness on the plates to be bonded. The local microroughness did not exceed 2 Å, and it did not noticeably affect the interface structure. Two types of the structure were subjected to a comparative analysis, (i) with a smooth interface prepared by standard direct-bonding technology, and (ii) with an interface displaying a regular relief. The strain level in type-II structures was found to be lower by more than an order of magnitude. A model is proposed to account for the observed reduction of elastic strains at the bonded sections of the interface in terms of elastic relaxation of the free surfaces in the relief voids through their deflection and displacement.

    Notes:
    Abstract A generalization of the Hall-Petch relationship is proposed. The generalized relationship takes account of the contributions from intergrain sliding, generation of lattice dislocations, and influence of disclination-like defects. From this approach, a critical size corresponding to a maximum of the Hall-Petch size dependence is obtained. The value of the critical size essentially depends on the state of boundaries and it explains contradictory results for the microhardness of nanocrystals (NCs), since grain-boundary sliding is facilitated in unrelaxed nanocrystals and constrained in aged ones.
