Book excerpt: To assist in the characterization of microstructural changes associated with irradiation damage in low alloy steels, the technique of quantitative x-ray mapping using a field emission gun scanning transmission electron microscope (FEG-STEM) equipped with an x-ray energy Dispersive spectrometer (XEDS) has been employed. Quantitative XEDS microanalyses of the matrix and grain boundaries of irradiated specimens have been compared with previous quantitative analyses obtained using 3D-Atom Probe Field-Ion Microscopy (3D-APFIM). In addition, the FEG-STEM XEDS maps obtained from the irradiated steel have revealed the presence of 2 to 3 nm Ni-enriched 'precipitates' in the matrix, which had previously been detected using 3D-APFIM. These quantitative FEG-STEM XEDS results represent the first direct and independent microchemical corroboration of the 3D-APFIM results showing ultra-fine irradiation-induced hardening features in low alloy steel.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Scanning electron microscope/energy dispersive spectroscopy (SEM/EDS) systems are popular for X-ray microanalysis due to its simple and fast operation. Recent years, which use cold field emission sources and silicon drift detectors, are highly capable X-ray imaging and quantitative microanalysis tools. However, the analytical efficiency and accuracy of SEM/EDS still have room for improvement. Regarding X-ray elemental mapping in particular, the top concern is to collect sufficient X-ray counts. Unfortunately, high count rates are usually achieved with sacrificing acquisition efficiency or spatial resolution. Regarding the quantitative X-ray microanalysis, the accuracy of EDS is constantly being questioned. Thus, the objective of this study is to optimize the SEM/EDS, making it a more efficient and accurate analytical instrument. In this study, X-ray mapping was performed on rare earth minerals (REMs), which contain various phases and complicated elemental constituents. The data was collected using a cold field emission SEM (CFE-SEM) equipped with an annular SDD (aSDD). The traditional elemental maps usually have excessive noise and limited phase information, so phase map analysis was performed instead. Compared with the conventional SDD, the aSDD has a larger solid angle, which produces high count rate and allows for efficient analysis at a low beam energy. The enhanced spatial resolution enables the accurate identification of REM phases down to one micron. In addition, the multivariate statistical analysis (MSA), i.e. the principal components analysis (PCA) and the blind source separation (BSS), was performed on the phase maps of REMs. This analysis reduces the noise and improves the phase identification accuracy, shortening the necessary acquisition timeThe f-ratio method, which is a recently developed quantitative analysis method for binary systems based on a CFE-SEM/EDS, is used. This method incorporates traditional EDS experiments and Monte Carlo simulations. Standards with known compositions are needed to calibrate the differences between experiments and simulations. In this study, the f-ratio method was applied to multi-element systems, including two Mg-Al-Zn alloys, and three standard minerals [kyanite (Al2SiO5), albite (NaAlSi3O8) and orthoclase (KAlSi3O8)]. The requirement of standard option was extended to any standard containing one or more target elements. The influences of the beam current, beam energy, and the standard composition were investigated. It is shown that the beam current does not have obvious impacts on the quantification results, so the f-ratio method is suitable for long acquisition, even when suffering from current instabilities. In addition, using beam-energy-dependent calibration factors, the f-ratio method can achieve a satisfactory accuracy"--

Download or read book Principles of Analytical Electron Microscopy written by Joseph Goldstein and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication in 1979 of Introduction to Analytical Electron Microscopy (ed. J. J. Hren, J. I. Goldstein, and D. C. Joy; Plenum Press), analytical electron microscopy has continued to evolve and mature both as a topic for fundamental scientific investigation and as a tool for inorganic and organic materials characterization. Significant strides have been made in our understanding of image formation, electron diffraction, and beam/specimen interactions, both in terms of the "physics of the processes" and their practical implementation in modern instruments. It is the intent of the editors and authors of the current text, Principles of Analytical Electron Microscopy, to bring together, in one concise and readily accessible volume, these recent advances in the subject. The text begins with a thorough discussion of fundamentals to lay a foundation for today's state-of-the-art microscopy. All currently important areas in analytical electron microscopy-including electron optics, electron beam/specimen interactions, image formation, x-ray microanalysis, energy-loss spectroscopy, electron diffraction and specimen effects-have been given thorough attention. To increase the utility of the volume to a broader cross section of the scientific community, the book's approach is, in general, more descriptive than mathematical. In some areas, however, mathematical concepts are dealt with in depth, increasing the appeal to those seeking a more rigorous treatment of the subject.

Download or read book Electron Probe Quantitation written by K.F.J. Heinrich and published by Springer Science & Business Media. This book was released on 1991-06-30 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1968, the National Bureau of Standards (NBS) published Special Publication 298 "Quantitative Electron Probe Microanalysis," which contained proceedings of a seminar held on the subject at NBS in the summer of 1967. This publication received wide interest that continued through the years far beyond expectations. The present volume, also the result of a gathering of international experts, in 1988, at NBS (now the National Institute of Standards and Technology, NIST), is intended to fulfill the same purpose. After years of substantial agreement on the procedures of analysis and data evaluation, several sharply differentiated approaches have developed. These are described in this publi cation with all the details required for practical application. Neither the editors nor NIST wish to endorse any single approach. Rather, we hope that their exposition will stimulate the dialogue which is a prerequisite for technical progress. Additionally, it is expected that those active in research in electron probe microanalysis will appreciate more clearly the areas in which further investigations are warranted.

Download or read book Physical Metallurgy written by R.W. Cahn and published by Elsevier. This book was released on 1996-02-09 with total page 2889 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fourth edition of a work which first appeared in 1965. The first edition had approximately one thousand pages in a single volume. This latest volume has almost three thousand pages in 3 volumes which is a fair measure of the pace at which the discipline of physical metallurgy has grown in the intervening 30 years. Almost all the topics previously treated are still in evidence in this version which is approximately 50% bigger than the previous edition. All the chapters have been either totally rewritten by new authors or thoroughly revised and expanded, either by the third-edition authors alone or jointly with new co-authors. Three chapters on new topics have been added, dealing with dry corrosion, oxidation and protection of metal surfaces; the dislocation theory of the mechanical behavior of intermetallic compounds; and (most novel) a chapter on polymer science for metallurgists, which analyses the conceptual mismatch between metallurgists' and polymer scientists' way of looking at materials. Special care has been taken throughout all chapters to incorporate the latest experimental research results and theoretical insights. Several thousand citations to the research and review literature are included in this edition. There is a very detailed subject index, as well as a comprehensive author index. The original version of this book has long been regarded as the standard text in physical metallurgy and this thoroughly rewritten and updated version will retain this status.

Available in PDF, EPUB and Kindle. Book excerpt: This book features reviews by leading experts on the methods and applications of modern forms of microscopy. The recent awards of Nobel Prizes awarded for super-resolution optical microscopy and cryo-electron microscopy have demonstrated the rich scientific opportunities for research in novel microscopies. Earlier Nobel Prizes for electron microscopy (the instrument itself and applications to biology), scanning probe microscopy and holography are a reminder of the central role of microscopy in modern science, from the study of nanostructures in materials science, physics and chemistry to structural biology. Separate chapters are devoted to confocal, fluorescent and related novel optical microscopies, coherent diffractive imaging, scanning probe microscopy, transmission electron microscopy in all its modes from aberration corrected and analytical to in-situ and time-resolved, low energy electron microscopy, photoelectron microscopy, cryo-electron microscopy in biology, and also ion microscopy. In addition to serving as an essential reference for researchers and teachers in the fields such as materials science, condensed matter physics, solid-state chemistry, structural biology and the molecular sciences generally, the Springer Handbook of Microscopy is a unified, coherent and pedagogically attractive text for advanced students who need an authoritative yet accessible guide to the science and practice of microscopy.

This book was released on 2012-12-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the transfer of chemical species through the aquatic environment the association with fine sediment particles is often of crucial importance. The n~ture, permanence and kinetics of this association is, in many cases, unknown yet it is central to any effort concerned with predicting the pathways of pollutant transfer and the fluxes along them. It is often unclear to precisely what surface, if any, a pollutant is attached. The transfer of species between surfaces and solution may be chemically or biochemically controlled. These processes may take place within a host framework which has a time and space dependent structure. The natural straining of this framework resulting from physical and chemical processes moves porewater and the dissolved species in it. Thus, to adequately predict the natural transfer of species within a cohesive sediment system the physical, biochemical and chemical processes must be dynamically coupled. This informal colloquium examined topics relevant to the associ ation of pollutant and sediment. These included the mineral particle surfaces and the surrounding ionic associations, methods of describing the particles and the physical, chemical, biochemical and biological processes operating in association with fine sediment substrates. The physical processes of sediment transport were deliberately excluded.

Download or read book Electron Probe Microanalysis written by Karl Zierold and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of electron probe microanalysis of biological systems is to identify, localize, and quantify elements, mass, and water in cells and tissues. The method is based on the idea that all electrons and photons emerging from an electron beam irradiated specimen contain information on its structure and composition. In particular, energy spectroscopy of X-rays and electrons after interaction of the electron beam with the specimen is used for this purpose. However, the application of this method in biology and medicine has to overcome three specific problems: 1. The principle constituent of most cell samples is water. Since liquid water is not compatible with vacuum conditions in the electron microscope, specimens have to be prepared without disturbing the other components, in parti cular diffusible ions (elements). 2. Electron probe microanaly sis provides physical data on either dry specimens or fully hydrated, frozen specimens. This data usually has to be con verted into quantitative data meaningful to the cell biologist or physiologist. 3. Cells and tissues are not static but dynamic systems. Thus, for example, microanalysis of physiolo gical processes requires sampling techniques which are adapted to address specific biological or medical questions. During recent years, remarkable progress has been made to overcome these problems. Cryopreparation, image analysis, and electron energy loss spectroscopy are key areas which have solved some problems and offer promise for future improvements.
