Properties of Aluminum Alloys

Properties of Aluminum Alloys PDF Author: John Gilbert Kaufman
Publisher: ASM International
ISBN: 1615031162
Category : Technology & Engineering
Languages : en
Pages : 569

Book Description
A compilation of data collected and maintained for many years as the property of a large aluminum company, which decided in 1997 to make it available to other engineers and materials specialists. In tabular form, presents data on the tensile and creep properties of eight species of wrought alloys and five species of cast alloys in the various shapes used in applications. Then looks at the fatigue data for several alloys under a range of conditions and loads. The data represent the typical or average findings, and though some were developed years ago, the collection is the largest and most detailed available. There is no index.

High Temperature Coatings

High Temperature Coatings PDF Author: Sudhangshu Bose
Publisher: Butterworth-Heinemann
ISBN: 0128047437
Category : Technology & Engineering
Languages : en
Pages : 418

Book Description
High Temperature Coatings, Second Edition, demonstrates how to counteract the thermal effects of rapid corrosion and degradation of exposed materials and equipment that can occur under high operating temperatures. This is the first true practical guide on the use of thermally protective coatings for high-temperature applications, including the latest developments in materials used for protective coatings. It covers the make-up and behavior of such materials under thermal stress and the methods used for applying them to specific types of substrates, as well as invaluable advice on inspection and repair of existing thermal coatings. With his long experience in the aerospace gas turbine industry, the author has compiled the very latest in coating materials and coating technologies, as well as hard-to-find guidance on maintaining and repairing thermal coatings, including appropriate inspection protocols. The book is supplemented with the latest reference information and additional support to help readers find more application- and industry-type coatings specifications and uses. - Offers an overview of the underlying fundamental concepts of thermally-protective coatings, including thermodynamics, energy kinetics, crystallography and equilibrium phases - Covers essential chemistry and physics of underlying substrates, including steels, nickel-iron alloys, nickel-cobalt alloys and titanium alloys - Provides detailed guidance on a wide variety of coating types, including those used against high temperature corrosion and oxidative degradation and thermal barrier coatings

Thermal Shock and Thermal Fatigue Behavior of Advanced Ceramics

Thermal Shock and Thermal Fatigue Behavior of Advanced Ceramics PDF Author: Gerold A. Schneider
Publisher: Springer Science & Business Media
ISBN: 9401582009
Category : Technology & Engineering
Languages : en
Pages : 575

Book Description
Recent developments in advanced ceramics are critically evaluated in respect to their thermal shock and thermal fatigue behavior from an interdisciplinary viewpoint by leading experts. The book covers the aspects of material development, mechanical and fracture mechanical models and experimental testing methods. Special emphasis is given to the influence of a rising crack resistance on the thermal shock behavior, novel irradiation testing methods for a quantitative characterization of the thermal shock and fatigue loading as well as detailed fracture mechanical models for single and multiple crack propagation. This book summarizes developments of the last decade concerning the thermal shock and thermal fatigue behavior of advanced ceramics. The scientific articles of the book were carefully arranged in order to achieve a textbook-like form which will be of great value to researchers and students.

Coatings for High-Temperature Structural Materials

Coatings for High-Temperature Structural Materials PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309176026
Category : Technology & Engineering
Languages : en
Pages : 102

Book Description
This book assesses the state of the art of coatings materials and processes for gas-turbine blades and vanes, determines potential applications of coatings in high-temperature environments, identifies needs for improved coatings in terms of performance enhancements, design considerations, and fabrication processes, assesses durability of advanced coating systems in expected service environments, and discusses the required inspection, repair, and maintenance methods. The promising areas for research and development of materials and processes for improved coating systems and the approaches to increased coating standardization are identified, with an emphasis on materials and processes with the potential for improved performance, quality, reproducibility, or manufacturing cost reduction.

Fatigue of Structures and Materials

Fatigue of Structures and Materials PDF Author: J. Schijve
Publisher: Springer Science & Business Media
ISBN: 1402068085
Category : Science
Languages : en
Pages : 627

Book Description
Fatigue of structures and materials covers a wide scope of different topics. The purpose of the present book is to explain these topics, to indicate how they can be analyzed, and how this can contribute to the designing of fatigue resistant structures and to prevent structural fatigue problems in service. Chapter 1 gives a general survey of the topic with brief comments on the signi?cance of the aspects involved. This serves as a kind of a program for the following chapters. The central issues in this book are predictions of fatigue properties and designing against fatigue. These objectives cannot be realized without a physical and mechanical understanding of all relevant conditions. In Chapter 2 the book starts with basic concepts of what happens in the material of a structure under cyclic loads. It illustrates the large number of variables which can affect fatigue properties and it provides the essential background knowledge for subsequent chapters. Different subjects are presented in the following main parts: • Basic chapters on fatigue properties and predictions (Chapters 2–8) • Load spectra and fatigue under variable-amplitude loading (Chapters 9–11) • Fatigue tests and scatter (Chapters 12 and 13) • Special fatigue conditions (Chapters 14–17) • Fatigue of joints and structures (Chapters 18–20) • Fiber-metal laminates (Chapter 21) Each chapter presents a discussion of a speci?c subject.

Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling

Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling PDF Author: J. Bressers
Publisher: Springer Science & Business Media
ISBN: 9401586365
Category : Technology & Engineering
Languages : en
Pages : 497

Book Description
The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.
