The theory of work hardening has had a turbulent history. In 1953, Cottrell [1] remarked that
''it was the first problem to be attempted by dislocation theory and may be the last to be …

Slip in face centred cubic (fcc) metals is well documented to occur on {111} planes in< 110>
directions. In body centred cubic (bcc) metals, the slip direction is also well established to …

Two of the key parameters that are useful for understanding the deformation kinetics in
metals with ultrafine grain (UFG) and/or nanocrystalline (nc) microstructure are the strain …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

The fundamental dislocation processes of glide, climb, and annihilation are studied on
diffusive time scales within the framework of a continuum field theory, the phase field crystal …

We study the texture evolution and deformation mechanisms in a Zr/Nb layered composite
using a combination of electron backscattered diffraction, dislocation density evolution …

Iron single crystals of wide range of orientations are tested in-situ at room temperature in
tension and compression using a Scanning Electron Microscope (SEM) and in tension using …

Simulations of dislocation dynamics in single crystals of hcp zirconium are presented with
emphasis on the hardening associated with prismatic slip at low temperature. Two original …

In this paper, the first investigation of the Orowan strengthening mechanism in the thermal
plastic regime of body-centered cubic (bcc) materials is made with dislocation dynamics …

The present paper is concerned with the development of a micromechanical model of the
hardening, rate-sensitivity and thermal softening of bcc crystals. In formulating the model, we …
