Intermittent dislocation density fluctuations in crystal plasticity from a phase-field crystal model
, 2014 Plastic deformation mediated by collective dislocation dynamics is investigated in the two-dimensional phase-field crystal model of sheared single crystals.

High Temperature Materials and Processes, 2016 We described a newly developed characterization technique that dislocation density could be individually determined for each texture component of plastically deformed metals by combining the line-profile analysis with the texture analysis by using X-ray ...

Effect of applied magnetic field on wear behaviour of martensitic steel
Journal of Materials Research and Technology, 2019 The effect of applied magnetic field on wear resistance of martensitic steel with different dislocation densities has been investigated. The wear resistance of martensitic steels improved under the applied magnetic field, while the improvement reduced as

Geometrically necessary dislocation densities in olivine obtained using high-angular resolution electron backscatter diffraction [PDF]
, 2016 © 2016 The AuthorsDislocations in geological minerals are fundamental to the creep processes that control large-scale geodynamic phenomena. However, techniques to quantify their densities, distributions, and types over critical subgrain to polycrystal ...

The dislocation configurational energy density in discrete dislocation plasticity
Journal of the Mechanics and Physics of Solids, 2019 Abstract Dislocation configurational energy is the term assigned to describe the elastically-stored energy associated with the interaction of dislocations and their structures. It is the energy which is over and above that from the summation of the dislocation line energies when considered isolated and non-interacting.

Modeling of Dislocation Structures in Materials
, 1996 A phenomenological model of the evolution of an ensemble of interacting dislocations in an isotropic elastic medium is formulated. The line-defect microstructure is described in terms of a spatially coarse-grained order parameter, the dislocation density

Homogenisation of a Row of Dislocation Dipoles from Discrete Dislocation Dynamics
, 2016 Conventional discrete-to-continuum approaches have seen their limitation in describing the collective behaviour of the multi-polar configurations of dislocations, which are widely observed in crystalline materials. The reason is that dislocation dipoles,

Dislocation density and graphitization of diamond crystals [PDF]
, 2002 Two sets of diamond specimens compressed at 2 GPa at temperatures varying between 1060 K and 1760 K were prepared; one in which graphitization was promoted by the presence of water and another in which graphitization of diamond was practically absent.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
