Interfaces and Plasticity

Dislocations were introduced into crystal physics, and particularly into the theory of plasticity, in 1934. For many years, they were the field of speculation of a small group of specialists, not considered seriously by real physicists and metallurgists. After W.T. Read Jr's fundamental work in 1953 and further developments by Cottrel, Friedel, Frank and Hirsch, dislocations had become part of the working vocabulary of solid-state physics and metallurgy.
