This book was released on 2012-12-06 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic diffusion in metals was first discovered some sixty-five years ago, and since then a considerable wealth of data has ac cumulated on diffusion in various systems. However, work prior to about the year 1940 is now mainly of historical interest, since ex periments were often carried out under experimental conditions and with methods of analysis leading to uncertainties in inter preting the measured diffusion coefficients. Data on diffusion rates are of importance in processes which are controlled by rates of atomic migration such as growth of phases and homogenization of alloys. In addition diffusion plays an important part in theories of such phenomena as oxidation, plastic deformation, sintering, and creep. A tremendous advance in diffusion studies was made possible by the availability of radioactive isotopes of sufficiently high spe cific activity after the second world war. Measurements of self diffusion rates then became possible using radioactive isotopes having the same chemical properties as the solvent material, and it also became possible to study tracer impurity diffusion when the concentration of the impurity is so small as not to alter the chemi cal homogeneity of the system. In the last ten to fifteen years the purity of materials used in diffusion studies has increased con siderably and the methods of analysis have become more stand ardized.

Book excerpt: "For the first time, this book unites the theory, experimental techniques and computational tools used to describe the diffusion of atoms, molecules and nanoparticles across metal surfaces. Starting with an outline of the formalism that describes diffusion on surfaces, the authors guide the reader through the principles of atomic movement, before moving on to diffusion under special circumstances, such as the presence of defects or foreign species. With an initial focus on the behaviour of single entities on a surface, later chapters address the movement of clusters of atoms and the interactions between adatoms. While there is a special emphasis on experimental work, attention is paid to the increasingly valuable contributions theoretical work has made in this field. This book has wide interdisciplinary appeal and is ideal for researchers in solid state physics, chemistry as well as materials science, and engineering"--Provided by publisher.
Download or read book Diffusion in Solid Metals and Alloys Diffusion in festen Metallen und Legierungen written by H. Bakker and published by Springer. This book was released on 1990-12-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interest in diffusion in solids is as old as physical metallurgy or materials science. It stems from application-oriented as well as from scientific reasons. First, a knowledge of diffusion is basic to an understanding of many microstructural changes that occur in solid matter at elevated temperatures. For processes like phase transformations, precipitation or dissolution of a second phase, recrystallization, oxidation, creep, annealing etc., solid state diffusion is fundamental and ubiquitous. The second reason for studying diffusion is to learn more about how atoms move in solid matter. Volume III/26 presents for the first time a comprehensive collection of diffusion data for solid metals and alloys. The critical compilation of data has resulted in tables and series of diagrams which show in 13 chapters data for the following properties: Self- and impurity-diffusion in metallic elements, self-diffusion in homogeneous binary alloys, chemical diffusion in binary and ternary alloys, diffusion in amorphous alloys, diffusion of interstitial foreign atoms like hydrogen, carbon, oxygen and nitrogen in metallic elements, mass and pressure dependence of diffusion, diffusion along dislocations, grain and interphase boundary diffusion, and diffusion on surfaces.

Download or read book Diffusion in Crystalline Solids written by G E Murch and published by Academic Press. This book was released on 2012-12-02 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffusion in Crystalline Solids addresses some of the most active areas of research on diffusion in crystalline solids. Topics covered include measurement of tracer diffusion coefficients in solids, diffusion in silicon and germanium, atom transport in oxides of the fluorite structure, tracer diffusion in concentrated alloys, diffusion in dislocations, grain boundary diffusion mechanisms in metals, and the use of the Monte Carlo Method to simulate diffusion kinetics. This book is made up of eight chapters and begins with an introduction to the measurement of diffusion coefficients with radioisotopes. The following three chapters consider diffusion in materials of substantial technological importance such as silicon and germanium. Atomic transport in oxides of the fluorite structure is described, and diffusion in concentrated alloys, including intermetallic compounds, is analyzed. The next two chapters delve into diffusion along short-circuiting paths, focusing on the effect of diffusion down dislocations on the form of the tracer concentration profile. The book also discusses the mechanisms of diffusion in grain boundaries in metals by invoking considerable work done on grain-boundary structure. The last two chapters are concerned with computer simulation, paying particular attention to machine calculations and the Monte Carlo method. The book concludes by exploring the fundamental atomic migration process and presenting some state-of-the-art calculations for defect energies and the topology of the saddle surface. Students and researchers of material science will find this book extremely useful.

Download or read book Modern M ssbauer Spectroscopy written by Yutaka Yoshida and published by Springer Nature. This book was released on 2021-01-19 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the latest Mössbauer spectroscopy research. It sheds light on various cutting-edge research subjects: (i) nuclear resonance scattering experiments implemented at synchrotron radiation facilities, e.g., ESRF, DESY and Spring-8; (ii) multidisciplinary materials research related to chemistry, biology, geoscience, molecular magnetism of metal complexes, batteries, and magnetism; (iii) novel imaging techniques based on probing diffusion in solids using Mössbauer spectroscopy. The first three chapters introduce recent research on modern Mössbauer spectroscopy, including nuclear resonant scattering experiments and development of related techniques at synchrotron accelerator facilities. Chapters 4 and 5 then demonstrate the applications of such pioneering techniques to chemistry, biology and geoscience. Chapters 6 and 7 describe the applications to new functional materials, i.e., metal complexes and Li- and Na-ion batteries, while the final two chapters are devoted to two important measuring techniques: Mössbauer spectroscopy under external magnetic fields, and microscopic Mössbauer techniques on diffusion in solids, which are expected to play an essential role in the investigation and characterization of magnetic structures and microstructures in materials. The cutting-edge content provides readers with quick updates on the latest research topics in the field, while the tutorial-style descriptions allow readers unfamiliar with Mössbauer spectroscopy to learn and implement the techniques. As such, the book is especially useful for advanced undergraduate and early graduate students who have recently been assigned to a laboratory.
Download or read book Diffusion in Ceramics written by Joshua Pelleg and published by Springer. This book was released on 2015-08-20 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an introduction to changes that occur in solids such as ceramics, mainly at high temperatures, which are diffusion controlled, as well as presenting research data. Such changes are related to the kinetics of various reactions such as precipitation, oxidation and phase transformations, but are also related to some mechanical changes, such as creep. The book is composed of two parts, beginning with a look at the basics of diffusion according to Fick's Laws. Solutions of Fick’s second law for constant D, diffusion in grain boundaries and dislocations are presented along with a look at the atomistic approach for the random motion of atoms. In the second part, the author discusses diffusion in several technologically important ceramics. The ceramics selected are monolithic single phase ones, including: A12O3, SiC, MgO, ZrO2 and Si3N4. Of these, three refer to oxide ceramics (alumina, magnesia and zirconia). Carbide based ceramics are represented by the technologically very important Si-carbide and nitride based ceramics are represented by Si-nitride which has been important in high temperature ceramics and gas turbine applications. The author presents a clear, concise and relatively comprehensive treatment of diffusion in ceramics for use by those at an advanced undergraduate level and beyond. It supports understanding of the basic behavior of materials and how to relate observed physical properties to microscopic understanding. The book also provides researchers with a handy collation of data relating to diffusion in ceramics and supports a fundamental understanding of atomic movements.
