This book concentrates on both understanding and development of nanocrystalline materials. The original relation that connects grain size and strength, known as the Hall-Petch relation, is studied in the nanometer grain size region. The breakdown of such a relation is a challenge. Why and how to overcome it? Is the dislocation mechanism still operating when the grain size is very small, approaching the amorphous limit? How do we go from the microstructure information to the continuum description of the mechanical properties?

James C. M. Li is professor of mechanical engineering and of materials science at Rochester University. James has published numerous papers and won many distinguished awards, including the Albert Easton White Distinguished Teacher Award.
"Ever since the development of novel processes to produce nanocrystalline materials, researchers have been active in enhancing mechanical properties by tailoring the material microstructure and composition. This is a seminal book edited by Professor James C. M. Li, the most authoritative scientist on the subject. It would be of great value to students, teachers and researchers working in the field of materials science and engineering."
