Book excerpt: This book comprehensively presents the concepts of neutron physics and imaging including neutron properties, neutron matter interaction, neutron imaging, comparison with X-ray and physics and design of neutron sources. It discusses how neutron imaging has gained importance as a powerful non-destructive technique to understand the internal structures of materials/engineered components in wide range of industries by increasing their applicability and efficiency. The book also covers the topics of neutron optics and detectors, basic principles of neutron radiography and tomography, related standards, safety, metrology and regulations in neutron imaging. The book presents applications of neutron imaging in the areas of aerospace industry, nuclear power and manufacturing industry, materials science and engineering, geomechanics, national security, biological, and medical domain. Given its scope, the book will be highly beneficial for postgraduate students, researchers and industry professionals working in the area of engineering and physics, especially non-destructive testing and non-destructive evaluation through neutron imaging.

This book was released on 1998 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen embrittlement describes a group of phenomena leading to the degradation of metal alloy properties. The hydrogen concentration in the alloy can be used as an indicator for the onset of embrittlement. A neutron tomography system has been optimized to perform nondestructive detection of hydrogen concentration in titanium aircraft engine compressor blades. Preprocessing of back projection images and postprocessing of tomographic reconstructions are used to achieve hydrogen concentration sensitivity below 200 ppm weight. This paper emphasizes the postprocessing techniques which allow automated reporting of hydrogen concentration.

Book excerpt: The hydrogen concentration in zirconium alloys used in nuclear fuel cladding can be determined quantitatively, rapidly and non-destructively with a spatial resolution of 25 ?m by neutron radiography. Because the total neutron cross section of hydrogen is more than one order of magnitude higher than that of zirconium, low concentrations of hydrogen can be measured. Calibration measurements have been performed and confirm the linear dependence of the total macroscopic neutron cross section on the hydrogen to zirconium atomic ratio as expected from theoretical analysis. The fast and non-destructive character of the method provides the possibility of in situ investigations. Examples of in situ investigations of the diffusion of hydrogen into Zircaloy-4 and of hydrogen uptake during steam oxidation are given. For the steam oxidation experiments a fast hydrogen uptake was found during the first 10 s. After this first step, the hydrogen concentration in the sample decreases slightly. If breakaway oxidation occurs, additional hydrogen absorption takes place. The hydrogen concentration can then increase by nearly one order of magnitude by this process. The influence of variations in the total gas flow and the steam flow on the hydrogen uptake was investigated, too.

Download or read book Determination of Hydrogen in Materials written by Pulat K. Khabibullaev and published by Springer. This book was released on 2006-04-11 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring the hydrogen content in materials is important both for research and for various applications in material and surface sciences, such as hydrogen embrittlement of steel, controlled thermonuclear reaction first wall studies, and changed material properties caused by dissolved hydrogen. Hydrogen is the most difficult atomic species to analyze by traditional methods, but nuclear physics methods are particularly suited for this purpose. President of the Uzbek SSR Academy of Sciences P.K. Khabibullaev and Professor B.G. Skorodumov discuss in this book the characteristics of these methods, such as lower detection limits, selectivity in respect to different isotopes, accuracy, depth resolution and maximum detection depth. Examples of applications that are dealt with include the determination of material humidity, the dating of objects, the study of hydrogen diffusion including non-stationary processes, and the investigation of changes in material properties like superconductivity, plasticity and electrical properties due to contamination by hydrogen.

This book was released on 2006-05-05 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for this book arose from my teaching, engineering, and - search experience in the non-power aspects of nuclear technology. The lack of a comprehensive textbook in industrial applications of radiation frustrated my students, who had to resort to a multitude of textbooks and research publications to familiarize themselves with the fundam- tal and practical aspects of radiation technology. As an engineer, I had to acquire the design aspects of radiation devices by trial-and-error, and often by accidental reading of a precious publication. As a researcher and a supervisor of graduate students, I found that the needed literature was either hard to find, or too scattered and diverse. More than once, I discovered that what appeared to be an exciting new idea was an old concept that was tried a few decades earlier during the golden era of “Atom for Peace”. I am hoping, therefore, that this book will serve as a single comprehensive reference source in a growing field that I expect will continue to expand. This book is directed to both neophytes and experts, and is written to combine the old and the new, the basic and the advanced, the simple and the complex. It is anticipated that this book will be of help in - viving older concepts, improving and expanding existing techniques and promoting the development of new ones.
