Summary

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 explores 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. A fantastic resource for senior undergraduate and graduate students of material sciences, materials engineering and materials chemistry, a solutions manual is also available for lecturers:www.wiley.com/go/rhodestechnology2e/

Author Biography

Martin Rhodes holds a Bachelor's degree in chemical engineering and a PhD in particle technology from Bradford University in the UK, industrial experience in chemical and combustion engineering and many years experience as an academic at Bradford and Monash Universities. He has research interests in various aspects of gas fluidization and particle technology, areas in which he has many refereed publications in journals and international conference proceedings. Martin is on the editorial boards of Powder Technology and KONA and on the advisory board of Advanced Powder technology. Martin has a keen interests in particle technology education and has published books and CDROM on Laboratory Demonstrations and directed continuing education courses for industry in the UK and Australia. He was co-founder of the Australasian Particle Technology Society. Martin has a Personal Chair in the Department of Chemical Engineering at Monash University, Australia, where he is presently Head of Department.
