The material in this book is based on invited and contributed pa pers presented at the NATO Advanced Research Workshop on INon-stoichio l metric Compounds held in Ringberg Castle, Rottach-Egern (Bavarian Alps), Germany, July 3-9, 1988. The workshop followed previous meetings held in Mogilany, Poland (1980), Alenya, France (1982), Penn State, USA (1984) and Keele University, UK (1986). The aim of these workshops is to present and discuss up-to-date knowledge in the study of non-stoichiometry and its effect on materials properties as well as to indicate the most urgent research pathways required in this field. Since the subject of non-stoichiometry is interdisciplinary, the workshops bring together solid state physicists and chemists, surface scientists, materials scientists, ceramists and metallurgists. The present workshop, which gathered 42 scientists of an inter national reputation, mainly considered the effect of surfaces, grain boundaries and structural defects on materials properties. From discus sions during this meeting it emerged that correct understanding of properties of ceramic materials requires urgent studies on the defect structure of the interface region. Progress in this direction requires the development of the interface defect chemistry. This is the task for materials scientists in the near future. The present proceedings includes both theoretical and experimen tal work on general aspects of non-stoichiometry, defect structure and diffusion in relation to the bulk and to the interface region of such materials as high tech ceramics, solid electrolytes, electronic cera mics, nuclear materials and high Tc oxide superconductors.

Materials Data for Cyclic Loading, Part B: Low-Alloy Steels presents materials data for cyclic loading which provide the basis for materials assessment by direct comparison of data or characteristic values and for estimating the crack initiation lives of low-alloy steels under constant and variable amplitude loading. The data include stress-strain curves, strain life curves, and mean stress parameter life curves for cyclic loading. Each data sheet takes up a maximum of four pages. The first page gives a description of the material and testing procedure. The chemical composition is always given in weight percent and corresponds to the values given in the literature referred to. The second and third pages show the diagrams for: stress-strain curves for monotonic and cyclic loading; strain life curve;, and mean stress (damage) parameter life curve according to the parameter of Smith, Watson and Topper. Unless indicated otherwise in the plots, the experiments were carried out at room temperature in laboratory air. The diagrams for the stress-strain relationships contain at the most three curves, one for monotonic loading and two for cyclic loading, the latter being evaluated from incremental step tests and constant amplitude tests. All three curves can be described approximately by an analytical function. This book will be of interest to materials scientists.

It is estimated that about 40% of the annual production of metals is used to repair or replace materials damaged by corrosion. Corrosion causes waste of the natural material and energy resources, it creates serious materials problems for many technologies and adversely affects almost every area of engineering. The use of metals in various aggressive environments has resulted in an extremely wide diversity of corrosion problems. This book presents a collection of concise reviews written by experts in the field on selected topics of metallic corrosion and on some aspects of interaction of hydrogen with metals. A comprehensive range of problems is examined including localized corrosion, high temperature corrosion in liquid metals and molten salts, transport control in corrosion processes, entry of hydrogen into metals, hydrogen embrittlement, and hydrogen reactions with metals. The variety of topics covered in the book will provide corrosion scientists, engineers, university lecturers and students alike with an interdisciplinary approach to solving problems of materials degradation and surface processes in metal corrosion.

An integral review is given in this book on the fatigue phenomenon covering the fundamentals of fatigue damage initiation, relevant factors influencing fatigue crack propagation and fatigue life, random load analysis, and simulation for theoretical and experimental fatigue life assessment. The entire chain of problems related to fatigue of metals and structural components is covered. Specifically, it describes the low-cycle plastic properties and statistically interprets the material stress reaction, examining original results of investigations on inelastic deformations under high cycle cyclic loading and correlating them with a number of use parameters. The limit states of bodies with primary defects and their resistance to fatigue crack propagation are discussed. Measurements, analysis and real-time modelling of operating loads for experimental fatigue life verification are reviewed as well as introducing some new fatigue damage accumulation hypotheses based on dissipated energy. Various operating and environmental factors of the fatigue life are analyzed, including temperature, metal structures, corrosive environment, stress-strain amplitudes and their changes, random load (strain) properties, stress gradient frequency, mean level, etc. The work is intended for all those involved in research and development in the metal, machine and structure fields.

Maintaining the integrity of nuclear power plants is critical in the prevention or control of severe accidents. This monograph deals with both basic groups of structural materials used in the design of light-water nuclear reactors, making the primary safety barriers of NPPs. Emphasis is placed on materials used in VVER-type nuclear reactors: Cr-Mo-V and Cr-Ni-Mo-V steel for RPV and Zr-Nb alloys for fuel element cladding. The book is divided into 7 main chapters, with the exception of the opening one and the chapter providing a phenomenological background for the subject of radiation damage. Chapters 3-6 are devoted to RPV steels and chapters 7-9 to zirconium alloys, analysing their radiation damage structure, changes of mechanical properties due to neutron irradiation as well as factors influencing the degree of their performance degradation. The recovery of damaged materials is also discussed. Considerable attention is paid to a comparison of VVER-type and western-type light-water materials. This monograph will be of great value to postgraduate students in nuclear engineering and materials science, and for designers and research workers in nuclear energy.

The aim of this book is to fill the gap in the scientific literature by providing a comprehensive overview on the surface and near-surface chemistry of oxide materials. Oxide materials are important in a wide range of technological applications, which has resulted in a large bibliography devoted to their properties. The range of practical applications of metal oxides has recently been significantly extended by the discovery of high T c oxide superconductors. Surface chemistry overlaps with several other disciplines and involves some specialized physical methods, therefore renown scientists active in various fields were invited to contribute to the book. The present volume involves surface characterization of metal oxides as well as surface and near-surface phenomena including gas-solid, solid-solid and liquid-solid interphases. Both basic problems and applied aspects are covered. The theoretical background of ideal and real surfaces as well as surface phenomena such as adsorption, segregation, interphase interactions, equilibration, etc., are dealt with. A comprehensive description is given of the most useful experimental techniques for studying surface and near-surface (grain boundary) chemistry of ceramic materials, oxide catalysts, semiconductors and other oxide materials of practical importance. The range of practical applications of metal oxides has recently been significantly extended by the discovery of high T c oxide superconductors. A special chapter is devoted to High T c oxide superconductors, which provides an up-to-date and thorough review of this currently ''hot topic'' which will be of great interest to a wide section of the scientific community.
