Spin current, 2nd edition

dislocations in ionic crystals and dislocations in anisotropic elastic media. The third and fourth parts discuss the interactions of dislocations with point defects and other dislocations, respectively; the part on interactions with point defects discusses the equilibrium defect concentrations (intrinsic point defects in equilibria with dislocations, elastic interaction effects and charged dislocations among other things), diffusive climb and glide, glide of jogged dislocations, dislocation motion in systems with supersaturated vacancies and effect of solute atoms on dislocation motion. The part on groups of dislocations discusses sources of dislocations, grain boundaries and interfaces (modelled as walls of dislocations and the energetics and interactions), dislocation pileps and cracks, dislocation intersections and barriers and deformation twinning. Each of the chapters in the book starts with a research highlight. The research highlights are followed by a summary of key developments of the given chapter. In the book, the theoretical developments are augmented with other relevant material; not only the experimental results are summarised, but also, wherever relevant, the computational aspects (such as atomistic and discrete dislocation dynamics studies) and their results are integrated. The material is discussed with mathematical sophistication. The chapters consist of several solved and unsolved exercises. Every chapter ends with a set of problems. The book also includes discussions on open and unsolved problems; for example, the section on mobility of dislocations discusses the problem of radiation of dislocations at high velocities (theoretically predicated but not observed experimentally). There are innumerable pictures, images, micrographs and schematics to help understand and visualise the material under discussion. There is plenty of room in the margin; the margins also contain highlights and notes for easy accessibility. There are a large number of foot notes which serve as pointers to literature as well as to indicate assumptions and approximations made to bring clarity to the derivations; there is even one indicating that the typographical errors in a published paper are being corrected in the section under discussion. In addition to the theoretical development (along with emphasis on computational aspects) and summary of experimental results, there are two important aspects of the book which make it an ideal reference book even for those who might be aware of the material: the book collects much data that is of interest and importance for further studies – such as surface and interface energies and dislocation core related data (effective core parameter, core energy and Peierls stress – obtained from atomic calculations); there are about 1400 references alphabetically arranged at the end of the book (in addition to the chapter wise bibliography). Finally, the book is hard bound and the production quality is excellent. Understanding the origins of material phenomena and properties in terms of defects in the material is probably the key to the study of materials science. The book by Anderson, Hirth and Lothe on the theory of dislocations, from this point of view, addresses crucial part of any materials scientist’s repertoire in a holistic (integrating the experimental, theoretical and computational aspects of the field) and mathematically sophisticated manner. Hence, I have no hesitations in recommending this book to advanced undergraduates, graduates, or early stage researchers for a detailed study as well as to established researchers as a standard reference of the field.
