F.R.N. Nabarro has had a profound impact on the development of workhardening theory. Albeit, on account of his opposition to the LEDS/LES theory, that may be recognized as an emerging new paradigm, this has not always been positive. The LEDS/LES para

A prime objective in the development of crystal dislocation theory has been, and at any rate should be, constitutive equations for practical use in the metal forming industry. Protracted controversies regarding workhardening theory have frustrated th

A general lesson learned in a scientific life time is presented, namely on how to judge the validity of a theory by the use of Occam's razor, and the application of this lesson to theoretical efforts in the area of the plastic deformation of solids.

Dislocations commonly form planar arrays that minimize the free interfacial energy between relatively mismatched crystal volumes. In epitaxy and phase transformations, the causative misfit is that between differences in lattice structure and/or orien

The combination of Newton's third law, action equals reaction, and of the second law of thermodynamics, leads to the LES (Low-Energy Structures) hypothesis, saying that among all potentially accessible structures, plastic deformation will generate th

The large size of Mg, and presumably also Li, substitutional atoms in aluminum leads to an abnormally high equilibrium vacancy concentration and results in planar glide in spite of high stacking fault energies and thus ease of cross slip. By contrast

The facts regarding “regular” deformation bands (DBs) outlined in Part I of this series of articles are related to the low-energy dislocation structure (LEDS) theory of dislocation-based plasticity. They prompt an expansion of the theory by inclu

The present state of knowledge regarding “regular” deformation bands (DBs) is reviewed in the light of some recent observations on DBs in compressed polycrystalline aluminum. These are slablike volume elements within which different selections of
