Glide in Imperfect Crystals Containing Various Obstacles

2 Glide in Imperfect Crystals Containing Various Obstacles 

Real crystals can contain a large variety of different types of point, line, and planar crystal defects and other entities, such as embedded particles, which interact with dislocations and can act as obstacles to glide. Solute atoms are good examples of point defects that hinder dislocation glide by acting as centers of dilation 

The host of interesting kinetic processes associated with the movement of dislocations through materials containing various obstacles to their motion is far too large to be described in this book. The reader is therefore referred to specialized texts [2, 7-9].
