Available in PDF, EPUB and Kindle. Book excerpt: The characterisation of microstructure is a cornerstone in the study of both natural and technological materials. In the widest sense this topic encompasses for all phases present: morphology, including size and shape distributions; chemical composition; and crystallographic parameters, including orientation and orientation relationships. A landmark advance for the materials community occurred with the genesis of 'microtexture', which for the first time provided integration of crystallographic parameters and other aspects of the microstructure. Microtexture can be defined as 'a population of crystallographic orientations whose individual components are linked to their location within the microstructure'. The term microtexture can also be applied to any experimental technique used to determine this information. Essentially, atomic planes in the sampled volume of specimen diffract a stationary beam of electrons. Analysis of the resulting diffraction pattern provides crystallographic information which can be related back to its position of origin. An estimated 95% of microtexture determination is by electron backscatter diffraction (EBSD) in a scanning electron microscope (SEM), with the remaining 5% contributed mainly by transmission electron microscopy (TEM) counterparts to EBSD. Evaluation determination is by electron backscatter diffraction (EBSD) in a scanning electron microscope (SEM), with the remaining 5% contributed mainly by transmission electron microscopy (TEM) counterparts to EBSD. Evaluation (indexing) of EBSD diffraction patterns and output of data in a variety of formats is in most cases fully automated. The most exciting EBSD output is an 'orientation map', which is a quantitative depiction of the microstructure in terms of its orientation constituents. Microtexture determination is now firmly established as the most comprehensive experimental tool for quantitative characterisation and analysis of microstructure, and is used extensively in both research and industry. Much has changed since this book was first published and the second edition has been completely rewritten to reflect these developments.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Introduction to Texture Analysis: Macrotexture, Microtexture, and Orientation Mapping broke new ground by collating seventy years worth of research in a convenient single-source format. Reflecting emerging methods and the evolution of the field, the second edition continues to provide comprehensive coverage of the concepts, practices, and applications of techniques used to determine and characterize texture. Providing a clear focus on scientific principles, this reference keeps mathematics to a minimum in covering both traditional macrotexture analysis and more modern electron-microscopy-based microtexture analysis. The authors integrate the two techniques and address the subsequent need for a more detailed explanation of philosophy, practice, and analysis associated with texture analysis. The book is organized into three sections: Fundamental Issues addresses terminology associated with orientations and texture, in addition to their representation. It also covers the diffraction of radiation, a phenomenon that is the basis for almost all texture analysis. Macrotexture Analysis covers data acquisition, as well as representation and evaluation related to the well-established methods of macrotexture analysis. Microtexture Analysis provides experimental details of the transmission or scanning electron microscope-based techniques for microtexture analysis. It also describes how microtexture data are evaluated and represented and explores the innovative topics of orientation microscopy and mapping, and advanced issues concerning crystallographic aspects of interfaces and connectivity. Completely revised and updated, this second edition of a bestseller is a rare introductory-level guide to texture analysis. It illustrates approaches to orientation measurement and interpretation and elucidates the fundamental principles on which measurements are based. This book is an ideal tool to help you develop a working understanding of the practice and applications of texture.
