Kurzbeschreibung
Introduction to Particle Technology , Second Edition provides a comprehensive introduction to the many concepts of this broad subject. Completely updated and revised, this new edition provides an excellent introduction to particle technology. Additional chapters have been added and case studies are provided alongside real-life industrial applications illustrating the techniques and theory.
In general terms, microstructural characterization is achieved by allowing some form of probe to interact with a carefully prepared specimen sample. The most commonly used probes are visible light, X-ray radiation and high-energy electron beams. These three types of probe form the basis for optical microscopy, X-ray diffraction and electron microscopy.
The book is an introduction to the expertise involved in assessing the microstructure of engineering materials and to the experimental methods used for this purpose. In the same way as the first edition, Microstructural Characterization of Materials - 2nd edition will explore the methodology of materials characterization under the three headings of crystal structure, microstructural morphology, and microanalysis. The principal methods of characterization including diffraction analysis, optical microscopy, electron microscopy, and chemical microanalytical techniques are treated in full. An additional chapter has been added to the new edition on surface probe microscopy and there are new sections on digital recording, processing, and analysis. The second edition has been updated, and has revised and expanded problems from the first edition to aid learning.
The book will appeal to senior undergraduate and graduate students of material sciences, materials engineering and materials chemistry. In addition, more advanced researchers will find the book useful as a general reference source.
