描述: The wide practical use of the diffusion barrier phenomenon in the various areas of science and modern engineering is impossible without the studying of all aspects of their creation, functioning and degradation. The present monograph covers specific and important aspect of the diffusion barriers damaging process - the deleterious effect of atomic-scale defects in the structure of diffusion barriers.

描述: "Manufacturing Technology and Materials Processing" is a core course for the undergraduate program: "Mechanical Engineering - Engineering Materials - Industrial Manufacture" in all reputed universities. This volume is designed for readers who are either engineering-degree students or practicing engineers in industry. This volume comprises of 19 chapters that are organized by dividing into four parts. Part I introduces to the Fundamentals of Materials and Manufacturing. Part II discusses Basic and Conventional Manufacturing Processes. Part III deals with Advanced Manufacturing Processes and Systems. Finally, in Part IV are explained Economic aspects and aspects of Quality Assurance of the manufacturing.

In this monograph, for the first time, results of systematic studies of cytoplasmic syncytial connections in the vertebrate and invertebrate nervous system are presented. It has been shown that in the nervous system, apart from chemical synapses and electrical membranous contacts, the third type of interneuronal communications exists — the cytoplasmic syncytial connection. Absolute criteria are developed, which allow revealing syncytial connections in light microscopy preparations and in tissue culture plexuses, as well as in electron microscopy investigations. For the first time, the method of artificial syncytial fusion of mass of living neurons in experiment was developed. It was shown that neurons, like cells of all other types, are capable for the enucleation with formation of karyoplasts and cytoplasts. This book is of interest to neurophysiologists, neuromorphologists, and neuropathologists, as well as to lecturers in the corresponding general courses about the neuron.

描述: This book is intended for a wide readership and mostly for specialists - builders, as well as graduate and undergraduate students of engineering sciences in universities. In this book the Authors outline the general statement of structural theory and consider on its basis the interrelations of structure and properties of major groups of building materials. By generalizing the data of numerous studies, the Authors refer to and analyze the results obtained by them in the Pridneprovsk Academy of Construction and Architecture and the National University of Water Management and Environmental Sciences (Ukraine).

描述: The book consists of introduction and two parts. In the first part electromagnetic transients caused by shorts, longitudinal and lateral asymmetry, technological process and conditions of electromagnetic compatibility are considered. The part two is devoted to electromechanical transients and to combined influence of the electromagnetic and electromechanical transients on power supply system operation stability.

描述: This volume presents a summary of relevant diffusion data. Enormous amount of research has been expended on the option of storing the hydrogen in solid metal alloys. The loading of metals with hydrogen, and its extraction, depends upon several processes. It is found that the slowest, and therefore the rate-determining process is hydrogen diffusion in the solid.

描述: Perhaps the best-known aspect of the behavior of metals, and indeed of most materials, is that they weaken with temperature. This weakening is however a problem in some applications. Only tungsten for instance, with its naturally high melting-point, was suitable for the manufacture of the filaments of incandescent light-bulbs. Even then, it was necessary to add oxide particles having a yethigher melting-point in order to prevent the weakening effect of grain-growth. These are alloys however which can be said to be weakened by heat, but nevertheless ‘hang on’ to enough strength to perform their task. The real boon would be an alloy which actually, as it were, ‘rose to the occasion’. Such a class of alloy exists, and is the subject of this book. It brings together everything which is known about the yield strength anomaly; both theoretically and experimentally.

描述: This monograph deals with the shape of Liesegang operator and its respective phase diagrams of spontaneous surges and analyzed properties of cluster attractors. It describes the influence of pulsation noise or self-organization current of gel systems in a magnetic field on singularities of optic parameters of yttrium oxyhydrate, as well as on kinetic curves of changes in optic density of oxyhydrate systems, sorptive properties of d- and f-elements, and the structural organization of their colloids. This monograph is meant for postgraduate students, magisters, researchers, and those interested in solid-state chemistry and physics.

描述: There are relatively few revolutions in the venerable and rather staid field of metallurgy. One can count among them the advent of metallic glasses, of superplastic metals, or of memory-alloys. The latest revolution involves the relatively staid topic of alloy formulation, but is all the more startling because the resultant materials break every long-cherished rule of alloy design. In particular, the famous empirical rules of Hume-Rothery are completely ignored. That is, in the archetypal high-entropy alloy, five metals are alloyed together in equal proportions regardless of atomic-size difference, valence or crystal structure. Commonsense would tell any experienced metallurgist that that could result only in a uselessly brittle mass of intermetallic compounds. But in a truly paradigm-shifting manner, Professor J.W.Yeh of Taiwan correctly predicted that a high configurational entropy could suppress the appearance of detrimental intermetallic compounds and lead to simple familiar microstructures having very useful properties. High-Entropy Alloys can exhibit, for instance, astounding hardness and strength and also have a very good corrosion resistance. The present book summarises the microstructures and properties of all of the high-entropy alloys.
