Download or read book Dislocation distributions in fatigued single crystals of 3 25 silicon iron written by Kent Randall Carson and published by . This book was released on 1966 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue tests were performed on single crystals of 3.25% silicon-iron oriented for single slip. The behavior of dislocations was studied in the early stages of the fatigue process as a function of temperature, number of cycles, and state of stress. A particular emphasis was placed upon observing tangle formation and growth. Part of the tests were performed by cycling about a zero mean stress in 4-point bending. Crystals were fatigued in this manner for various numbers of cycles at both 298K and 495K. The dislocation distributions were investigated by the etch pit technique and electron transmission microscopy. The remainder of the tests were performed in alternating tension. As before, cyrstals were fatigued for various numbers of cycles at both 298K and 425K. In this case, the dislocation distributions were investigated solely by electron transmission microscopy.

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.

Download or read book Fatigue of Metal Crystals Part I Extension of Fatigue Life of Crystals Through Control of Substructure written by S. Weissmann and published by . This book was released on 1966 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structural changes in silver and aluminum crystals fatigued in bending were studied by metallographic, X-ray and electron microscope methods. The fatigue process may be divided into three consecutive broad stages characterized by an increase in dislocation density, formation of substructure and fragmentation into cell structure, respectively. Strain and temperature are the two parameters controlling the development of the dislocation substructure. Both a decrease in strain or an increase in temperature cause growth of subgrains and cells, while variation of the parameters in the opposite direction has an inverse effect on the structure. The growth of subgrains and cells resulting from cycling with lowered strain amplitude is attributed to a mechanism involving dislocation climb. The life of single crystals of silver was nearly two orders of magnitude greater than that of aluminum. The introduction of a grain boundary reduced the life for both to the same level, thus eliminating the beneficial effect of low stacking fault energy on fatigue life. The deleterious effect of boundaries introduced as stress-raisers was, however, eliminated by alternating the cycling between high and low strain amplitudes. The fatigue life of aluminum crystals could thus be extended fourfold. The technique of alternating cycling produced internal decoration of the areas with high internal stresses. (Author).
