Summary

This book provides an overview and also a description of the latest developments in the theory of grain boundary geometry, experimental aspects of data collection and data processing. The book covers all aspects of electron optics techniques (SEM, TEM) to the study of grain boundaries in metals and alloys (and by extension to semiconductors, ceramics and minerals).
