Abstract:
Light microscopy, electron backscatter diffraction and transmission electron microscopy is employed to investigate dislocation structure and impurity precipitation in commonly occurring dislocation clusters as observed on defect-etched directionally solidified multicrystalline silicon wafers. The investigation shows that poligonised structures consist of parallel mostly similar, straight, well-ordered dislocations, with minimal contact-interaction and no evidence of precipitate decoration. On the other hand, disordered structures consist of various dislocation types, with interactions being common. Decoration of dislocations by second phase particles is observed in some cases. Enhanced recombination activity of dislocations may therefore be a result of dislocation interaction forming tangles, microscopic kinks and jogs, which can serve as heterogeneous nucleation sites that enhance metallic decoration.

Abstract:
The configuration of dislocation wall structures and the interactions between dislocations and dislocation walls play a significant role in the understanding of deformation processes in metals. Samples of single-crystal aluminum deformed by tensile-straining (15%) were analyzed using TEM. In tensile-deformed (15%) single crystal aluminum, a cell structure is well developed and dislocations in the cell boundaries consist of either one set of Burgers vector or two sets of Burgers vector. The three-dimensional image of cell wall structure, misorientation angle across the cell boundaries and the Burgers vectors of dislocations in the cell boundaries are characterized.

Abstract:
The structure of the “star” defect in 4H-SiC substrates and its effects on the extended defect structures in the epilayers were studied by molten KOH etching and transmission x-ray topography. Star defects consist of a center region with high densities of threading dislocations (both edge and screw types) and six arms of dislocation arrays extending along <11-20> directions. In addition, multiple linear dislocation arrays extending perpendicular to the off-cut direction were observed in the epilayers. Dislocation arrays extending along <11-20> directions are consistent with the slip bands generated by the prismatic slip: a/3<11-20>{1-100}. Bands of linear dislocation arrays extending perpendicular to the off-cut direction correspond to the threading edge dislocations nucleated during epitaxial growth.

Abstract:
A fatigue crack growth test was conducted in a polycrystalline copper. Dislocation structure formed near an intergranular fatigue crack was investigated by electron channelling contrast imaging (ECCI) method. The ECCI method enables us to observe dislocations lying under surface using a scanning electron microscope. The fatigue crack in the copper specimen was grown along both grain boundaries and slip bands inside grain. The ECCI observations revealed that both the vein dislocation structure and the cell structures were formed near the grain boundaries. The formations of different dislocation structures near boundaries could be interpreted in terms of the plastic strain incompatibility.

Several studies have been carried out regarding the influence of dislocations on device characteristics; however, most of them had been limited to pseudo-vertical structures using high pressure high temperature (HPHT) insulating material as the substrate. In this study, we have investigated the influence of dislocations to the devices using vertical structure SBD on p+ HPHT substrate. SBDs were selectively fabricated on specific dislocation areas. The SBD fabricated on the threading dislocation area indicated fatal influence of the dislocation on the device characteristics.

Abstract:
A problem related to the development of instability of a homogeneous state in an ensemble of screw dislocations under plastic deformation of metals is considered . The study of the development of instability and structure formation in the dislocation ensemble is carried out on the basis of the method developed for charged particles in plasma and associated with the correlation interaction of electrons and positively charged ions. Accordingly, the screw dislocation ensemble is represented as a system of dislocations with an opposite Burgers vector, i.e., as a plasma-like medium with opposite dislocation charges. The total dislocation charge of the dislocation ensemble is equal to zero due to the law of conservation of the Burgers vector. In this situation, the elastic field of dislocations is “cut off”. The stress field of a single dislocation is shielded by a uniformly distributed dislocation “background” and is characterized by a certain effective potential. It is found that at long distances it decreases exponentially. Therefore, the value in the argument of the falling potential can be considered as the radius of screening of the elastic field of dislocations. It is shown that the screening radius is equal to the correlation radius, which makes it possible to construct a two-particle correlation function and find the energy of the correlation interaction of dislocations. A system of kinetic equations for a dislocation ensemble is formulated, taking into account the elastic and correlation interaction of dislocations, as well as the processes of their generation and annihilation. The criterion of instability of the homogeneous distribution of dislocations for the formulated system of equations is established. The instability criterion is met under the condition that the dislocation density exceeds a certain critical value that depends on the square of the flow stress and material constants (such as the Burgers vector modulus and shear modulus, as well as indirectly, the packing defect energy). In the framework of linear analysis, it is shown that when one system of sliding screw dislocations is taken into account, a one – dimensional periodic dislocation dissipative structure is formed at the moment of instability occurrence, and when multiple sliding is taken into account, solutions appear in the form of various variants of polyhedral lattices (cellular structures). It is established that the characteristic size of the cellular structure coincides with the experimental dependence both qualitatively and quantitatively ( the cell size is proportional to the square root of the dislocation density, and the proportionality coefficient is about ten). It is shown that the origin of spatially inhomogeneous dislocation structures, based on correlation instability, depends mainly on the features of the elastic interaction of dislocations and is not critical to the choice of the mechanisms of their kinetics (i.e., the mechanisms of generation, annihilation, and runoff of dislocations).

Abstract:
Dislocations in silicon produced by plastic deformation are generally dissociated into partials. 60° dislocations (Burgers vector type 1/2[101]) are dissociated into 30°(Burgers vector type 1/6[211]) and 90°(Burgers vector type 1/6[112]) dislocations. The 30° partials may be either of “glide” or “shuffle” type. Lattice images of the 30° dislocation have been obtained with a JEM 100B, and with a JEM 200Cx. In the aforementioned experiments a reasonable but imperfect match was obtained with calculated images for the “glide” model. In the present experiment direct structure images of 30° dislocation cores have been obtained with a JEOL 4000EX. It is possible to deduce the 30° dislocation core structure by direct inspection of the images. Dislocations were produced by compression of single crystal Si (sample preparation technique described in Alexander et al.).

The dynamic mechanical property and microstructure evolution of commercial pure titanium with initial lamellar dislocation boundary structures were studied at different strain rate compression. The experiments were conducted to the cylindrical specimens using Gleeble-3500 thermal mechanical simulation machine at room temperature. With increasing of the strain rate, strain rate strengthening effect was found in the material. New dislocation boundary structures along impact direction were generated which perpendicular to initial dislocation boundary. Then the S bands boundary structure was formed by interaction between new and initial dislocations. It can be supposed that initial dislocation boundary are sheared and kinked by new dislocation slipping.

Abstract:
We are now entering what one might consider the third phase of study of dislocations by transmission electron microscopy (TEM). The first phase, in the 1950’s and 1960’s led to classifications of dislocation behavior, concepts of low angle boundaries, equilibrium nodes, and dislocation extension, for example. The second, with the advent of the weak-beam technique, produced improved estimates of stacking fault energy on the basis of dislocation extension, revealed more types of extended dislocation configurations, particularly in ordered intermetallic compounds and inorganic compounds, and revealed finer scale partial dislocations such as misfit dislocations and grain boundary dislocations. With improved resolution for both imaging and direct lattice resolution, we can now be thought to be entering a third phase where information on even finer scale core structure of dislocations might be revealed.The improvement in direct core structure resolution is exciting to those working on the physics of dislocation configurations or on dislocation motion and mechanical properties because of the possibility of direct confirmation of mechanisms and models that have heretofore only been tested by indirect correlations.

AbstractThe dislocation distribution of high-quality single-crystal gallium nitride (GaN) films grown by the hybrid vapor phase epitaxy was analyzed. This study examined the domain structure of GaN from the dislocation distribution on the macroscale by optical microscopy. The surface structure of GaN consisted of domains with microcolumns as the substructure. The inner domains contained a lower density of dislocations but a large number of these dislocations were observed along the domain boundaries. The existence of a domain boundary structure doubly increased the total dislocation density.

Abstract:
Afin de mieux appréhender la plasticité des alliages métalliques, il est important de pouvoir décrire à l'échelle atomique les interactions entre dislocations et solutés et d’en déduire l’effet sur la mobilité des dislocations. Au cours de cette thèse, nous nous sommes intéressés aux métaux de transition cubiques centrés (CC), et en particulier au fer, en présence de solutés interstitiels. A l’aide de calculs en Théorie de la Fonctionnelle de la Densité (DFT), la structure de cœur de la dislocation vis de vecteur de Burgers b=½<111> a été étudiée dans le fer en présence de solutés de bore, carbone, azote et oxygène et dans les métaux CC des groupes 5 (V, Nb et Ta) et 6 (Mo, W) en présence de carbone. Nous avons mis en évidence dans le fer et les métaux du groupe 6 une reconstruction du cœur de la dislocation en présence de solutés, associée à une très forte énergie d’attraction dislocation/soluté. Un comportement différent a été observé pour le groupe 5, la configuration la plus stable pour le carbone étant un site octaédrique proche de la dislocation, sans reconstruction de cœur. Cette tendance de groupe a été reliée à la structure des mono-carbures. Les conséquences des interactions fortement attractives dans le fer en présence de carbone ont ensuite été développées. D’une part la ségrégation d’équilibre du carbone proche du cœur de la dislocation a été étudiée à l’aide de modèles en champ moyen et de simulations Monte Carlo. D’autre part, la mobilité de la dislocation décorée a été étudiée en modélisant le mécanisme de double décrochement, en lien avec des observations expérimentales en microscopie électronique à transmission
In order to improve our understanding of alloy plasticity, it is important to describe at the atomic scale the dislocation-solute interactions and their effect on the dislocation mobility. This work focuses on the body-centered cubic (BCC) transition metals, in particular Fe, in presence of interstitial solute atoms. Using Density Functional Theory (DFT) calculations, the core structure of the screw dislocation of Burgers vector b=½<111> was investigated in iron in presence of boron, carbon, nitrogen and oxygen solute atoms, and in BCC metals from group 5 (V, Nb, Ta) and 6 (Mo, W) in presence of carbon solutes. A core reconstruction was evidenced in iron and group 6 metals, along with a strong attractive dislocation-solute interaction energy. A different behavior was observed in group 5 metals, for which the most stable configuration for the carbon atom is an octahedral site in the vicinity of the dislocation, without any core reconstruction. This group tendency was linked to the structure of mono-carbides. Consequences of the strongly attractive dislocation-solute interactions in Fe(C) were then investigated. First the equilibrium segregation close to the dislocation core was studied using a mean-field model and Monte Carlo simulations. Then, the mobility of the dislocation in presence of carbon atoms was investigated by modeling the double-kink mechanism with DFT, in relation with experimental data obtained with transmission electron microscopy

ENGLISH ABSTRACT: This is an exploratory investigation into the discourse-pragmatic function(s) of the so-called Left-Dislocation construction in Biblical Hebrew. This inquiry is a part of a larger investigation into the nature and function of word order variation in Biblical Hebrew. In light of past research on Biblical Hebrew word-order variation, specifically concerning Left-Dislocation constructions, it is concluded that a re-analysis of Left-Dislocation constructions in Biblical Hebrew is called for. Advancements within the fields of cognitive-functional linguistics and discourse-pragmatics (information-structure) have afforded numerous avenues towards a more comprehensive cognitive-oriented frame of reference for ascertaining the functions of Biblical Hebrew word order variation. The discourse-pragmatic and cognitive-functional notion of information-structure serves as the basis for the theoretical framework employed in the present investigation. Information-structure is principally concerned with the question as to why grammars of natural language offer speakers a variety of morphosyntactic and prosodic options for expressing the same propositional content. Since the Left-Dislocation construction is a universal syntactic phenomenon, typological information regarding the form and function of Left-Dislocation constructions across languages served as a critical source of insight into the prototypical formal features and functional domains of the construction within Biblical Hebrew. The insights garnered from cross-linguistic data informed the parameters employed in the construction and construal of a random data-set of one hundred cases of Left-Dislocation drawn from the narrative portions of the Hebrew Bible stretching from Genesis to 2 Chronicles. The investigation of our data-set, within the confines of a discourse-pragmatic framework, reveals that Left-Dislocation constructions in Biblical Hebrew are principally employed to facilitate the topic-promotion of identifiable but inactive discourse-referents. These referents could be the primary or secondary topics of the sentences in which they are used.
AFRIKAANSE OPSOMMING: Hierdie studie is 'n verkennende ondersoek na die diskoerspragmatiese funksie(s) van sogenaamde linksverskuiwing ('Left-Dislocation') konstruksies in Bybelse Hebreeus. Hierdie vraagstelling vorm deel van 'n meer omvattende ondersoek na die aard en funksie van woordorde-variasies in Bybelse Hebreeus. Na aanleiding van 'n uitvoerige literatuurstudie oor die funksie(s) van woordorde-variasies in Bybelse Hebreeus, veral met betrekking tot linksverskuiwingskonstruksies, is tot die gevolgtrekking gekom dat 'n heranalise van linksverskuiwingskonstruksies in Bybelse Hebreeus nodig is. Vooruitgang op die gebiede van kognitiewe-funksionele taalkunde, en tekspragmatiek (informasiestruktuur) het dit moontlik gemaak om 'n meer omvattende kognitief-georiënteerde verwysingsraamwerk vir die bepaling van die funksie(s) van Bybels-Hebreeuse woordorde-variasies te formuleer. Die diskoerspragmatiese en kognitiewe-funksionele opvatting van informasiestruktuur dien as die basis vir die teoretiese raamwerk wat in die huidige ondersoek gebruik is. Informasiestruktuur is hoofsaaklik gemoeid met die vraag waarom die grammatika van natuurlike taal aan sprekers 'n verskeidenheid van morfosintaktiese en prosodiese opsies bied vir die uitdrukking van dieselfde proposisionele inhoud. Aangesien die linksverskuiwingskonstruksie 'n universele sintaktiese verskynsel is, is taaltipologiese inligting oor die vorm en funksie van die linksverskuiwingskonstruksie gebruik om insig te kry in die prototipiese formele eienskappe en funksies van die konstruksie in Bybelse Hebreeus. Aan die hand van bg. taaltipologiese insigte is parameters geformuleer aan die hand waarvan 'n ewekansige monster voorbeelde van linksverskuiwing uit verhalende tekste uit Genesis tot 2 Kronieke ondersoek is. Daar is bevind dat linksverskuiwing in Bybelse Hebreeus hoofsaaklik aangewend word om identifiseerbare, maar onaktiewe diskoersreferente te promoveer as topieks. Hierdie referente mag primêre of sekondêre topieks wees.

Full text
Abstract:
The strengths of metallic multilayers, composed of alternating layers of soft metals such as Cu and Nb, approach the theoretical limit of material strength when the bilayer periods are on the order of a few nanometers. We have investigated the damage mechanisms in these ultra-high strength nanolayered composite materials subjected to monotonic deformation. Large strain plastic deformation such as room temperature rolling does not lead to any dislocation cell structure formation within the layers indicating that the deformation and dislocation storage mechanisms in nanostructured materials are completely different from the bulk. In bulk metals, dislocation pile-ups lead to heterogeneous slip, but in nano-materials, deformation by single dislocations on closely spaced glide planes results in more homogeneously distributed slip. The implications of the high tensile strengths and homogeneous slip on the fatigue properties of nanolayered materials are also discussed.

Abstract:
The mechanical properties of crystalline solids are inherently a function of their microstructure which in turn is governed by processing of the material. Although advances in understanding the structure-property relationships have been achieved, more basic research to expand the knowledge base is certainly needed. Recent work on exploring the strengthening effect of particles and grain-boundaries in a crystalline solid, using the fundamental approach of dislocation dynamics, is presented. Whenever appropriate, comparisons to experimental findings or theoretical models are made. The work demonstrates the power and limitations of such simulation methodology. In particular some basic physics of the interaction between dislocations and these microstructural features are revealed.
