Crystallography and Crystal Defects

Extensively revised and updated, this new edition of a classic text presents a unified approach to crystallography and to the defects found within crystals. The book combines the classical and exact description of symmetry of a perfect crystal with the possible geometries of the major defects-dislocations, stacking faults, point defects, twins, interfaces and the effects of martensitic transformations. A number of important concepts and exciting new topics have been introduced in this second edition, including piezoelectricity, liquid crystals, nanocrystalline concepts, incommensurate materials and the structure of foamed and amorphous solids. The coverage of quasicrystalline materials has been extended, and the data tables, appendices and references have been fully updated.

Reinforcing its unrivalled position as the core text for teaching crystallography and crystal defects, each chapter includes problem sets with brief numerical solutions at the end of the book. Detailed worked solutions, supplementary lecture material and computer programs for crystallographic calculations are provided online (http: //booksupport.wiley.com).

Anthony Kelly is an Emeritus Professor and a Distinguished Research Fellow in the Department of Materials Science and Metallurgy at Cambridge University (UK). Professor Kelly has been employed in universities, in governmental science (National Physical Laboratory) and in industry (ICI). He was Vice-Chancellor of the University of Surrey (UK) and while there he established the Surrey Research Park. In 1963 with Robin Nicholson he produced the first synthesis relating type of dispersion and work hardening characteristics of metals. This has become an SCI citation classic. Since 2000 his main research interest is in using composite principles to control and to modify the thermal expansion coefficients of materials. He is the principal author of the two previous very successful editions of ＂Crystallography and Crystal Defects＂ and of other books and has a worldwide reputation in materials science.

Dr. Kevin Knowles is senior lecturer at Department of Materials Science and Metallurgy at the University of Cambridge (UK). He received his DPhil at Oxon (UK) on aspects of the crystallography of martensitic transformations. Dr. Knowles has lectured and supervised a course on crystallography to third year undergraduates and he lectures and supervises a course on plasticity and deformation processing to undergraduates. The research interests of his group focus on the relationship between microstructure and the mechanical and electronic properties of engineering ceramics.
