Interaction energy of interface dislocation loops in piezoelectric bi-crystals

Theoretical and Applied Mechanics Letters, 2017
Interface dislocations may dramatically change the electric properties, such as polarization, of the piezoelectric crystals. In this paper, we study the linear interactions of two interface dislocation loops with arbitrary shape in generally anisotropic ...

Simplification of selective imaging of dislocation loops: diffraction-selected on-zone STEM

Philosophical Magazine Letters
Contrary to the conventional belief that, in transmission electron microscopy (TEM), selective and sharp imaging of dislocation loops can be realized only by accurate tilting of a specimen from the condition that the symmetrical axis of incident electron

Dislocation loop bias and void swelling in irradiated α-iron from mesoscale and atomistic simulations

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 ...

Characterization of dislocation loops in hydrogen ion-implanted Fe-Cr alloy annealed at different temperatures

工程科学学报, 2019
Reduced-activation ferritic/martensitic (RAFM) steels, based on Fe-Cr alloys, have been considered to be one of the most promising candidate structural materials for future fusion reactors.

In-situ TEM study of loop evolution in FeCrAl alloy under Fe+ irradiation: Effects of temperatures, dislocations and precipitates

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.

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+

SMARANDACHE LOOPS [PDF]

, 2002
The theory of loops (groups without associativity), though researched by several mathematicians has not found a sound expression, for books, be it research level or otherwise, solely dealing with the properties of loops are absent.

Dislocation dynamics - analytical description of the interaction force between dipolar loops [PDF]

, 2007
summary:The interaction between dislocation dipolar loops plays an important role in the computation of the dislocation dynamics. The analytical form of the interaction force between two loops derived in the present paper from Kroupa’s formula of the ...
