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."
