Interactions between butterfly-like prismatic dislocation loop pairs and planar defects in Ni3Al
, 2021 Understanding the interactions between planar defects and complex dislocation structures in a material is of great significance to simplify its design. In this paper, we show that, from an atomistic perspective, by using molecular dynamics simulations on

Interrelation between Dislocation Loops and an Edge Dislocation
MATERIALS 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.

Microstructural Characterization of Reactor Pressure Vessel Steels
Metals, 2023 Ion irradiation is a promising tool to emulate neutron-irradiation effects on reactor pressure vessel (RPV) steels, especially in the situation of limited availability of suitable neutron-irradiated material.

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

Annealing of dislocation loops in dislocation dynamics simulations
IOP 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.

Nano-sized prismatic vacancy dislocation loops and vacancy clusters in tungsten
Nuclear 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]
PLoS 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 ...

Influence of pre-implanted helium on dislocation loop type in tungsten under self-ion irradiation [PDF]
, 2018 Transmission electron microscopy with in-situ ion irradiation has been used to examine dislocation loop formation during self-ion irradiation of pristine W and samples pre-implanted with He.

Topological events on wave dislocation lines: birth and death of small loops, and reconnection
, 2007 In three-dimensional space, a wave dislocation, that is, a quantized (optical) vortex or phase singularity, is a line zero of a complex scalar wavefunction.
