Overview

In the 1950s the direct observation of dislocations became possible, stimulat­ ing the interest of many research workers in the dynamics of dislocations. This led to major contributions to the understanding of the plasticity of various crys­ talline materials. During this time the study of metals and alloys of fcc and hcp structures developed remarkably. In particular, the discovery of the so-called in­ ertial effect caused by the electron and phonon frictional forces greatly influenced the quantitative understanding of the strength of these metallic materials. Statis­ tical studies of dislocations moving through random arrays of point obstacles played an important role in the above advances. These topics are described in Chaps. 2-4. Metals and alloys with bcc structure have large Peierls forces compared to those with fcc structure. The reasons for the delay in studying substances with bcc structure were mostly difficulties connected with the purification techniques and with microscopic studies of the dislocation core. In the 1970s, these difficulties were largely overcome by developments in experimental techniques and computer physics. Studies of dislocations in ionic and covalent bonding materials with large Peierls forces provided infonnation about the core structures of dislocations and their electronic interactions with charged particles. These are the main subjects in Chaps. 5-7.

Describes the plastic deformation of various types of crystals over a wide temperature range in terms of the dynamic properties of dislocations. The major topics include the softening of metals at the superconducting transition, the photoplastic effects in semiconductor crystals, and creep deformation in metals and composites.
