LACBED characterization of dislocation loops [PDF]
Philosophical Magazine, 2006 The characterization of the amplitude and sign of the Burgers vector of perfect or partial dislocations from large-angle convergent-beam electron diffraction (LACBED) patterns is now a routine technique following the original idea proposed by Cherns and Preston [Proceedings of ICEM-11, Kyoto, Japan, pp. 721–722 (1986)].

BIAS OF BASAL DISLOCATION LOOP IN ZIRCONIUM
Problems 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.

Metals, 2022 The neutron irradiation of Fe-based fusion and fission reactor materials leads to an increase in ductile-to-brittle transition temperature with a decrease in upper shelf energy. It is well known that Cu content has a strong influence on the embrittlement

Communications Materials, 2023 Dislocation loops are ubiquitous in irradiated materials, and dislocation loop bias plays a critical role in void swelling. However, due to complicated interactions between dislocation loops and point defects, it is challenging to evaluate the bias ...

Nuclear Analysis, 2022 Fe13.5Cr4.7Al alloy was irradiated in-situ with 400 keV Fe+ in TEM at RT and 748 K. The evolution of dislocation loops under the influence of temperatures, irradiation dose, dislocation lines and precipitates were characterized in detail.

The collapse of defect cascades to dislocation loops [PDF]
Journal of Nuclear Materials, 1987 We describe a number of experiments that we have recently performed to investigate the collapse of defect cascades to dislocation loops. This important ion and neutron irradiation phenomenon has been studied with in situ ion bombardment using the High Voltage Electron Microscope-Ion Accelerator Facility at Argonne National Laboratory in Cu3Au, Cu, and ...

Effect of aluminum content on dislocation loops in model FeCrAl alloys
Nuclear Materials and Energy, 2019 Five kinds of iron-chromium-aluminum (FeCrAl) alloy samples with different contents of aluminum (Al)—Fe-12Cr, Fe-12Cr-2Al, Fe-12Cr-4Al, Fe-12Cr-6Al, and Fe-12Cr-8Al—were designed and prepared. All samples were then irradiated with 200 keV argon ions (Ar2+

Annihilation and sources in continuum dislocation dynamics
Materials Theory, 2018 Continuum dislocation dynamics (CDD) aims at representing the evolution of systems of curved and connected dislocation lines in terms of density-like field variables. Here we discuss how the processes of dislocation multiplication and annihilation can be

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.
