Book excerpt: The research performed under these Grants involved the development and application of the positorn annihilation technique to defect studies in metals. The experiments performed during the last three years divide into three categories: (a) the study of the applicability of the simple trapping model to positron annihilation in pure lead as a function of temperature; (b) the study of vacancy-impurity interactions in Pb(Cd) and Pb(Tl) alloys, in order to test the excitonic model of 'fast diffusion' of some impurities in Pb; and (c) the design and testing of multidetector angular correlation setup to perform momentum density measurements in metals with hydrogen, in order to study the role of hydrogen in the electronic structure of pure metals.

Book excerpt: Electron and Positron Spectroscopies in Materials Science and Engineering presents the advances and limitations of instrumentations for surface and interface probing useful to metallurgical applications. It discusses the Auger electron spectroscopy and electron spectroscopy for chemical analysis. It addresses the means to determine the chemistry of the surface. Some of the topics covered in the book are the exo-electron emission; positron annihilation; extended x-ray absorption fine structure; high resolution electron microscopy; uniaxial monotonic deformation-induced dislocation substructure; and analytical electron microscopy. The mechanistic basis for exo-electron spectroscopy is covered. The correlation of fatigue and photoyield are discussed. The text describes the tribostimulated emission. A study of the quantitative measurement of fatigue damage is presented. A chapter is devoted to the fracture of oxide films on aluminium. Another section focuses on the positron annihilation experimental details and the creep-induced dislocation substructure. The book can provide useful information to scientists, engineers, students, and researchers.

Download or read book Positron Profilometry written by Jerzy Dryzek and published by Springer Nature. This book was released on 2023-09-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of positron profilometry, specifically focusing on the analysis of defect depth distribution in materials. Positron profilometry plays a crucial role in understanding and characterizing defects in a wide range of materials, including metals, semiconductors, polymers, and ceramics. By analyzing the depth distribution of defects, researchers can gain insights into various material properties, such as crystal structure, defect density, and diffusion behavior. The author's extensive research spanning a period of two decades has primarily centered on subsurface zones. These regions, located beneath the surface and subjected to various surface processes, play a crucial role in generating defect distributions. Three experimental techniques and their data analysis are described in detail: a variable-energy positron beam (VEP) called sometimes a slow positron beam, a technique called implantation profile depth scanning (DSIP), and a sequential etching (SET) technique. The usability of these techniques is illustrated by many examples of measurements by the author and others.

This book was released on 1994-11-24 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to identify, discuss, and evaluate the applications of positron spectroscopy to materials science. Many applications to material science are identified. As there is need for intense sources of monoenergetic positrons in order for the field to reach its full potential, several designs for such sources are reported. Recommendations for policies and actions that will promote the transfer of positron spectroscopy technology to private industry have been worked out.

Download or read book Positron Spectroscopy of Solids written by Società italiana di fisica and published by IOS Press. This book was released on 1995 with total page 807 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lifetime of a positron inside a solid is normally less than a fraction of nanosecond. This is a very short time on a human scale, but is long enough to enable the positron to visit an extended region of the material, and to sense the atomic and electronic structure of the environment. Thus, we can inject a positron in a sample to draw from it some signal giving us information on the microscopic properties of the material. This idea has been successfully developed in a number of positron-based techniques of physical analysis, with resolution in energy, momentum, or position. The complex of these techniques is what we call now positron spectroscopy of solids. The field of application of the positron spectroscopy extends from advanced problems of solid-state physics to industrial applications in the area of characterization of high-tech materials. This volume focuses the attention on the physics that can be learned from positron-based methods, but also frames those methods in a wider context including other experimental approaches. It can be considered as a textbook on positron spectroscopy of solids, the sort of book that the newcomer takes for his approach to this field, but also as a useful research tool for the expert.

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.
