Methods of scientific investigation can be divided into two categories: they are either macroscopic or microscopic in nature. The former are generally older, classical methods where the sample as a whole is studied and various local prop erties are deduced by differentiation. The microscopic methods, on the other hand, have been discovered and developed more recently, and they operate for the most part on an atomistic scale. Glancing through the shelves of books on the various scientific fields, and, in particular, on the field of physical metallurgy, we are surprised at how lit tle consideration has been given to the microscopic methods. How these tools provide new insight and information is a question which so far has not at tracted much attention. Similar observations can be made at scientific confer ences, where the presentation of papers involving microscopic methods is often pushed into a far corner. This has led users of such methods to organize their own special conferences. The aim of this book is to bridge the present gap and encourage more interaction between the various fields of study and selected microscopic meth ods, with special emphasis on their suitability for investigating metals. In each case the principles of the method are reviewed, the advantages and successes pointed out, but also the shortcomings and limitations indicated.

Electron Microscopy of Interfaces in Metals and Alloys examines the structure of interfaces in metals and alloys using transmission electron microscopy. The book presents quantitative methods of analysis and reviews the most significant work on interface structure over the last 20 years. It provides the first book description of the methods used for quantitative identification of Burgers vectors of interfacial dislocations, including the geometric analysis of periodicities in interface structure and the comparison of experimental and theoretical electron micrographs. The book explores low- and high-angle grain boundaries and interphase interfaces between neighboring grains, emphasizing interfacial dislocations and rigid-body displacements to the structure and properties of interfaces. It also analyzes the use of two-beam images and diffraction patterns for analysis and studies n-beam lattice imaging. The book includes numerous worked examples of the analysis of the structure of grain boundaries and interphase interfaces, which are particularly useful to those who need to consider the nature of intercrystalline interfaces.

Containing over 1,200 representative micrographs and the information and explanatory text that makes them really useful, including composition, condition, etchant, magnification, and more than 100 graphs and tables, this 'how to' book not only gives everyday working examples, but also discusses the relationship between the constitution, metallurgy, and microstructure of various carbon steel products. Contents: Nomenclature of Phases and Constituents; Phase Transformations; Low-Carbon Irons and Steels; Annealing and Normalizing; Spheroidization and Graphitization; Austenitization; Transformation of Austenite; Tempering of Martensite; Welding; Surface Oxidation, Decarburation and Oxidation Scaling; Glossary of Terms; EtchingMethods; ConversionTables; Index.

This book covers state-of-the-art techniques commonly used in modern materials characterization. Two important aspects of characterization, materials structures and chemical analysis, are included. Widely used techniques, such as metallography (light microscopy), X-ray diffraction, transmission and scanning electron microscopy, are described. In addition, the book introduces advanced techniques, including scanning probe microscopy. The second half of the book accordingly presents techniques such as X-ray energy dispersive spectroscopy (commonly equipped in the scanning electron microscope), fluorescence X-ray spectroscopy, and popular surface analysis techniques (XPS and SIMS). Finally, vibrational spectroscopy (FTIR and Raman) and thermal analysis are also covered.

David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

Materials Characterization Using Nondestructive Evaluation (NDE) Methods discusses NDT methods and how they are highly desirable for both long-term monitoring and short-term assessment of materials, providing crucial early warning that the fatigue life of a material has elapsed, thus helping to prevent service failures. Materials Characterization Using Nondestructive Evaluation (NDE) Methods gives an overview of established and new NDT techniques for the characterization of materials, with a focus on materials used in the automotive, aerospace, power plants, and infrastructure construction industries. Each chapter focuses on a different NDT technique and indicates the potential of the method by selected examples of applications. Methods covered include scanning and transmission electron microscopy, X-ray microtomography and diffraction, ultrasonic, electromagnetic, microwave, and hybrid techniques. The authors review both the determination of microstructure properties, including phase content and grain size, and the determination of mechanical properties, such as hardness, toughness, yield strength, texture, and residual stress. - Gives an overview of established and new NDT techniques, including scanning and transmission electron microscopy, X-ray microtomography and diffraction, ultrasonic, electromagnetic, microwave, and hybrid techniques - Reviews the determination of microstructural and mechanical properties - Focuses on materials used in the automotive, aerospace, power plants, and infrastructure construction industries - Serves as a highly desirable resource for both long-term monitoring and short-term assessment of materials

Optical microscopy is one of the most valuable--but under utilized--tools for analyzing fiber reinforced polymer matrix composites. This hands-on instructional book covers everything: sample preparation, microscopic techniques, and applications. The power of optical microscopy to study the microstructure of these heterogeneous, anisotropic materials is illustrated with over 180 full color images.
