As a relatively simple top–down technique to produce nanomaterials in bulk, severe plastic
deformation became a new way of transforming the microstructure of the material. When …

Viscoplastic behavior of metallic materials is manifested by collective behavior of lattice
defects at multiple length scales. The full gamut of length scales, from atomic to …

Research trends in metal plasticity over the past 25years are briefly reviewed. The myriad of
length scales at which phenomena involving microstructure rearrangement during plastic …

Long-length ultrafine-grained (UFG) Ti rods are produced by equal-channel angular
pressing via the conform scheme (ECAP-C) at 200° C, which is followed by drawing at 200° …

A new model is proposed that aims to capture within a single modelling frame all the main
microstructural features of a severe plastic deformation process. These are: evolution of the …

Crystalline defects (eg, dislocations, disclinations and grain boundaries) play a critical role
in determining the mechanical and functional properties of metallic materials. From a …

Aspects of a constitutive model for characterizing crystalline metals containing a distribution
of dislocation and disclination defects are presented. Kinematics, balance laws, and general …

The effect of severe plastic deformation (SPD) on grain refinement and strain hardening in
polycrystalline metals is studied quantitatively. The decrease in size of dislocation cells and …

A modelling scheme is presented to predict recrystallisation textures of aluminium alloys. It is
assumed that the formation of textures during recrystallisation is governed by both oriented …

Two aluminium plates with different hot band textures were cold rolled to moderate thickness
reductions (55 and 60%). The formation of a rolling texture was analyzed quantitatively by …
