Unraveling deformation mechanisms around FCC and BCC nanocontacts through slip trace and pileup topography analyses [PDF]

open access: yes, 2017
Nanocontact loadings offer the potential to investigate crystal plasticity from surface slip trace emissions and distinct pileup patterns where individual atomic terraces arrange into hillocks and symmetric rosettes.

Horizontal instability after acromioclavicular joint reduction using the two-hole technique is preferred over the loop technique: a single-blind randomized clinical trial [PDF]

open access: yesClinics in Shoulder and Elbow, 2022
Background Most acromioclavicular joint (ACJ) injuries are caused by direct trauma to the shoulders, and various methods and techniques are used to treat them; however, none of the options can be considered the gold standard.

BIAS OF BASAL DISLOCATION LOOP IN ZIRCONIUM

open access: yesProblems of Atomic Science and Technology, 2021
An analytical expression for the elastic interaction energy of radiation point defects of the dipole type with the basal dislocation loop of the hcp metal is obtained using the Green's function method for hexagonal crystals in the Krener approach.

Nano-sized prismatic vacancy dislocation loops and vacancy clusters in tungsten

open access: yesNuclear Materials and Energy, 2018
The vacancies produced in high energy collision cascades of irradiated tungsten can form vacancy clusters or prismatic vacancy dislocation loops. Moreover, vacancy loops can easily transform into planar vacancy clusters.

"Conjugate channeling" effect in dislocation core diffusion: carbon transport in dislocated BCC iron. [PDF]

open access: yesPLoS ONE, 2013
Dislocation pipe diffusion seems to be a well-established phenomenon. Here we demonstrate an unexpected effect, that the migration of interstitials such as carbon in iron may be accelerated not in the dislocation line direction ξ, but in a conjugate ...

Nanoindentation investigation on the dislocation generation at incipient plasticity in a high carbon-added high-entropy alloy

open access: yesJournal of Materials Research and Technology, 2023
High-content interstitial carbon addition has been proven to regulate the dislocation behavior in high-entropy alloys (HEAs) during deformation, thereby overcoming the strength-ductility trade-off, but its exact mechanism is still unclear.

Interplay between electronic topology and crystal symmetry: Dislocation-line modes in topological band-insulators [PDF]

open access: yes, 2014
We elucidate the general rule governing the response of dislocation lines in three-dimensional topological band insulators. According to this ${\bf K}\text{-}{\bf b}\text{-}{\bf t}$ rule, the lattice topology, represented by dislocation lines oriented in

Interrelation between Dislocation Loops and an Edge Dislocation

open access: yesMATERIALS TRANSACTIONS, 2005
Since it has recently become an important subject to study the interrelation between a dislocation loop and a straight edge dislocation because of dynamic behaviors of small dislocation loops under irradiation condition, the simulation studies were made in model Fe lattice.

Annealing of dislocation loops in dislocation dynamics simulations

open access: yesIOP Conference Series: Materials Science and Engineering, 2009
We report of 3-dimensional discrete dislocation dynamics (DDD) simulations of dislocation loops coarsening by vacancy bulk difiusion. The calculation is based upon a model which couples the difiusion theory of vacancies to the DDD in order to obtain the climb rate of the dislocation segments.

On the non-uniform motion of dislocations: The retarded elastic fields, the retarded dislocation tensor potentials and the Li\'enard-Wiechert tensor potentials

open access: yes, 2012
The purpose of this paper is the fundamental theory of the non-uniform motion of dislocations in two and three space-dimensions. We investigate the non-uniform motion of an arbitrary distribution of dislocations, a dislocation loop and straight ...
