内容説明
Dislocations are lines of irregularity in the structure of a solid analogous to the bumps in a badly laid carpet. Like these bumps, they can be easily moved, and they provide the most important mechanism by which the solid can be deformed. They also have a strong influence on crystal growth and on the electronic properties of semiconductors.

内容説明
It is clear that disclination theory has not, or not yet, shown the power of physical explanation that has come from dislocation theory. However, there are many indications that its importance will grow. There is increasing interest in the structure of highly deformed metals, and their deformation obviously involves large mutual rotations of neighbouring elements. There is a strong, but not remarkably successful, activity in the theory of the formation of dislocation patterns during deformation, and these patterns are essentially disclinations. This volume contains four chapters: Chapter 44 illustrates the great advances which have occurred in the electron microscopy of dislocations, reporting on both the current theoretical position and the most accurate experimental observations. Chapter 45 gives a thorough analysis of the internal friction arising from the production and motion of kinks in dislocations lying in Peierls valleys. Chapter 46 treats another problem of dislocation dynamics, concluding that the processes are essentially different in f.c.c. and b.c.c. metals.
Chapter 47 discusses a topic which has been studied more vigorously in the Soviet Union than in the West, providing a summary of experimental observations on various kinds of rotational deformation together with a comprehensive bibliography. A detailed account of the elastic theory of disclinations is also presented here in a single chapter.
