Dislocations are defects in the crystal structure of important engineering materials, such as metals, ceramics and semi-conductors, that strongly influence the properties of these materials. Research ...

"Precipitation"(20 pp.), and "Fracture" (4 pp.). The papers of the first part are concerned mainly with the deformation of metals associated with movement of dislocations. Dislocation theory has ...

Many important properties of metals are now understood to result from a kind of imperfection in crystal lattices that is called a dislocation. The theory is helping to transform metallurgy from an ...
