This book was released on 1971 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dislocation configurations in slices of material taken ahead of the fatigue crack tip in copper single crystals were observed through transmission electron microscopy. These observations revealed: (a) a distinct transition in configuration as a region within approximately 250 microns of the crack tip was approached and (b) a reduction in dislocation cell size with decreasing distance from the crack tip similar in form to cell-size-vs-fatigue-stress-increase curves. These observations lend support to the concept of a distinct 'plastic zone' in the vicinity of the fatigue crack tip, with associated blunting-type crack propagation mechanisms. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report includes: DISLOCATION CONFIGUATIONS IN DEFORMED SILVER SINGLE CRYSTALS, by H.J. Levinstein and W.H. Robinson. 1962. Ag single crystals oriented for single slip were deformed incrementally in both simple shear and tension, and the dislocation arrangements were observed after each increment of strain by optical examination of the etch pitted surface or by examining replicas of these surfaces by electron microscopy. in addition, some observations were made on specimens deformed in compression. For a given specimen several increments of strain were made during stage I of the deformation and also duing stage II. The principal facts which emerged from these observations are that stage I is characterized by slip bands consisting of clusters of dislocations which are cellular in appearance. The segments of these clusters which are straight are very short, probably no more than 1 microns, and a given portion of a dislocation moves only a short distance, of the order of 5 to 10 microns, before being stopped. These results agree with those of transmission electron microscopy of thin foils taken from bulk specimens which have been strained. But they do not agree with observations on thin foils strained in the electron microscope. (Author).

Download or read book Deformation Substructure of Copper Single Crystals After Explosive Loading as Disclosed by Electron-Optical and X-Ray Methods written by V. A. Greenhut and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compressively shock-loaded copper single crystals were examined employing complementary methods of X-ray diffraction, X-ray topography (XRT), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The defect structures induced depended on the crystal orientation relative to the direction of shock propagation and also upon the existence or absence of a reflected tensile wave. TEM disclosed that the defect structure induced by compressive shock loading consisted of clusters of microtwins alternating with a tangled dislocation substructure. Failure zones did not occur. The induced defect structure exhibited a low net macroscopic misorientation which amounted to less than two degrees of arc and the misorientation of the twinned regions with respect to the adjacent dislocation substructure was less than 1/2 degree of arc. By contrast specimens subjected to a reflected tensile pulse exhibited a failure zone and the defect structure in its vicinity showed a substantial macroscopic misorientation. In addition, a high incidence of porosity was observed by SEM. The pores had octahedral shape with facets corresponding to close-packed planes. Structural details observed within the pores were identified as twinned regions. (Author).

Download or read book Fundamental Aspects of Dislocation Interactions written by G. Kostorz and published by Elsevier. This book was released on 2013-09-03 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Aspects of Dislocation Interactions: Low-Energy Dislocation Structures III covers the papers presented at a European Research Conference on Plasticity of Materials-Fundamental Aspects of Dislocation Interactions: Low-Energy Dislocation Structures III, held on August 30-September 4, 1992 in Ascona, Switzerland. The book focuses on the processes, technologies, reactions, transformations, and approaches involved in dislocation interactions. The selection first offers information on work softening and Hall-Petch hardening in extruded mechanically alloyed alloys and dynamic origin of dislocation structures in deformed solids. Discussions focus on stress-strain behavior in relation to composition, structure, and annealing; comparison of stress-strain curves with work softening theory; sweeping and trapping mechanism; and model of dipolar wall structure formation. The text then ponders on plastic instabilities and their relation to fracture and dislocation and kink dynamics in f.c.c. metals studied by mechanical spectroscopy. The book takes a look at misfit dislocation generation mechanisms in heterostructures and evolution of dislocation structure on the interfaces associated with diffusionless phase transitions. Discussions focus on dislocation representation of a wall of elastic domains; equation of equilibrium of an elastic domain; transformation of dislocations; and theoretical and experimental background. The selection is a valuable reference for readers interested in dislocation interactions.
