Plastic deformation of gallium arsenide
… to determine the validity of Haasen's model of plastic deformation for GaAs over an extended range of temperatures and to observe the relation between the dislocation density in the deformed samples and the deformation variables. The experimental results show a discrepancy with the predictions …

Plastic Deformation in Complex Crystal Structures
… toughness is desirable. In complex crystals plasticity, and hence toughness, is limited by the energy increases that occur as linear defects, dislocations, move. This is known as the lattice resistance. By understanding the factors controlling the lattice resistance in complex crystal …

Crystal-plastic deformation and chemical evolution of clinoamphibole
… undulose to patchy extinction and (100) deformation twinning surrounded by a mantle of recrystallized grains. In addition intragranular grains also occur within the cores. TEM analysis of the host grains revealed high densities of dislocations, dislocation arrays/subgrain boundaries …

The plastic deformation of alloys based on aluminum titanide
The thermal stability of a dispersion of rare-earth oxide particles in Ti and Ti$\sb3$Al matrices has been considered analytically and determined experimentally. The solubility product for the formation of erbia (Er$\sb2$O$\sb{3)}$ in a Ti matrix has been calculated using known thermodynamic data …

Structural evolution during the plastic deformation of nanostructured steel
Nanostructured bainitic steels represent a major advance in technology, because it is now possible to produce very large quantities of three-dimensional objects containing an incredible density of interfaces. This can be done at a reasonable cost so that thousands of tonnes can actually be …

Atomistic simulations of elastic-plastic deformation of amorphous polymers
… behavior and the molecular-level origins of plastic deformation of an amorphous glassy polymer were studied using atomistic simulations. Understanding of the molecular response will aid the development of physics-based continuum level models for these materials. A polyethylene-like molecular …

Computer modelling of plastic deformation and fracture in heterogeneous systems.
The results from a computational investigation of plastic deformation and fracture in austenitic steel are presented. A lattice model representing the continuum mechanical behaviour in three-dimensions is developed. The model is shown to recover the governing equations for continuum elasticity …

Processing of aluminium and titanium alloys by severe plastic deformation
Severe plastic deformation (SPD) techniques are applied to polycrystalline materials to significantly refine their grain sizes which lead normally to an enhancement of the material properties. Equal-channel angular pressing (ECAP) and high pressure torsion (HPT) were considered as very important …

Severe plastic deformation in highly immiscible copper alloys: self-organization
Severe plastic deformation (SPD) techniques such as equal channel angular pressing (ECAP), high pressure torsion (HPT), high energy ball milling (BM), accumulative roll bonding (ARB), are well known to refine the microstructures of metals and alloys into non-equilibrium states with nanometer-size …
