Download or read book Grain Boundary Segregation in Metals written by Pavel Lejcek and published by Springer Science & Business Media. This book was released on 2010-07-20 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.

This book was released on 2008-08-13 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain growth is the result of the collective migration of the grain boundaries of a polycrystal. Since grain boundaries are very complex elements, grain growth is complex as well. The mathematical description of the grain boundary requires four parameters in the two-dimensional case and eight parameters in the threedimensional one. The evolution of the microstructure in the course of grain growth is determined by the grain boundary mobility and energy; both properties depend on all the parameters for the definition of the grain boundary. Since triple lines, quadruple points and chemical composition play an important role, grain boundary becomes even more complex. The modeling of the grain growth requires the consideration of all the factors that affect grain growth. In the present dissertation, a Vertex Model for the simulation of two- and three-dimensional grain growth is implemented. The two-dimensional model was corroborated with classic basic theories on grain growth. Simulation on normal grain growth showed scaling behavior und a deviation of less than 1% when compared with the von Neumann-Mullins relationship. Furthermore, the model validated the theory on the finite mobility of the triple junctions from Gottstein and Shvindlerman and with this the model showed its applicability for the simulation of more complex granular aggregates with a finite triple junction mobility. The model also allows the use of experimental data. For instance, it was utilized for the reproduction of an experimental setting of magnetic influenced grain growth in pure titanium samples. The results of the simulation demonstrated that a magnetic field can determined the texture and grain growth kinetics of magnetic anisotropic metals. Simulation can also help to understand unexpected experimental results. For example, it was explained by means of molecular static and vertex model simulation the faceting of certain grain boundaries in aluminum. For this purpose, the grain boundary energy was obtained from molecular-static simulation and subsequently used in Vertex simulation. The results showed that the faceting of the grain boundaries can be attributed to the anisotropy of the grain boundary energy with the inclination angle. In turn, the 3D model was utilized to study the effect of the boundary junctions on three-dimensional grain growth. For this purpose a special configuration that allows the steady-state motion of the grain boundaries was used. The simulation results showed a very good agreement with the theoretical expectations and demonstrated that the finite mobility of the quadruple junctions can drag grain boundary migration. However, it was also found that triple lines drag more effectively grain growth.
Download or read book Grain Boundary Migration in Metals written by Gunter Gottstein and published by CRC Press. This book was released on 1999-06-17 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of adjacent materials at the boundary where they meet is an essential aspect of creating new engineering materials. Grain Boundary Migration in Metals is an authoritative account of the physics of grain boundary motion, written by two highly respected researchers. They provide a comprehensive overview of current knowledge regarding the migration process and how it affects microstructure evolution, focusing their treatment exclusively on the properties and behavior of grain boundaries with well defined geometry and crystallography. With their emphasis on applications-such as the characterization of microstructure and texture, recrystallization, and grain growth-the authors effectively fill the gap between the physics of grain boundary motion and its engineering practicality. The need for better microstructural design motivates permanent thrust for research in the field, and continued rapid progress appears inevitable. Grain Boundary Migration in Metals provides a solid foundation in the phenomena and serves as a valuable reference for professionals in materials science, solid state physics, and any industry engaged in metals production and the heat treatment of metals and alloys.
Download or read book Recrystallization and Related Annealing Phenomena written by F.J. Humphreys and published by Elsevier. This book was released on 2012-12-02 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annealing of deformed materials is of both technological importance and scientific interest. The phenomena have been most widely studied in metals, although they occur in all crystalline materials such as the natural deformation of rocks and the processing of technical ceramics. Research is mainly driven by the requirements of industry, and where appropriate, the book discusses the extent to which we are able to formulate quantitative, physically-based models which can be applied to metal-forming processes.The subjects treated in this book are all active research areas, and form a major part of at least four regular international conference series. However, there have only been two monographs published in recent times on the subject of recrystallization, the latest nearly 20 years ago. Since that time, considerable advances have been made, both in our understanding of the subject and in the techniques available to the researcher.The book covers recovery, recrystallization and grain growth in depth including specific chapters on ordered materials, two-phase alloys, annealing textures and annealing during and after hot working. Also contained are treatments of the deformed state and the structure and mobility of grain boundaries, technologically important examples and a chapter on computer simulation and modelling. The book provides a scientific treatment of the subject for researchers or students in Materials Science, Metallurgy and related disciplines, who require a more detailed coverage than is found in textbooks on physical metallurgy, and a more coherent treatment than will be found in the many conference proceedings and review articles.
