Movement of Dislocation Loops in Lithium Fluoride
Journal of Applied Physics, 1958 Very refined experiments on the movement of single dislocation loops in lithium fiuoride crystals, as revealed by etch pits, have been reported. In this note a somewhat more detailed interpretation is given for one particularly signiflcant experiment. (W.D.M.)

"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 ...

DISLOCATION DIPOLES AND DISLOCATION LOOPS
Le Journal de Physique Colloques, 1966 Basic theoretical ideas on the properties of two special dislocation configurations, dislocation dipoles and prismatic dislocation loops, are presented. Some of the author's recent results, based mostly on the application of the model of elastic continuum on these crystalline defects, are also given.

Grain size, size-distribution and dislocation structure from diffraction peak profile analysis [PDF]
, 2002 Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite ...

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

Ion Irradiation Defects and Hardening in FeCrAl Alloy
Metals, 2022 The self-ion irradiation experiments of FeCrAl and Y−FeCrAl alloys are carried out at 330 °C to 1–10 displacements per atom (dpa). The formation of dislocation loops in these alloys is investigated by transmission electron microscopy (TEM) and nano ...

Climb kinetics of dislocation loops in aluminium
Philosophical Magazine, 1968 Abstract The annealing kinetics of dislocation loops in quenched aluminium has been studied using transmission electron microscopy techniques. An influence of the vicinity of the foil surface on the rate of climb was confirmed. The apparent activation energy for climb of faulted loops was found to be 1·18 ± 0·02 ev and the pre-exponential factor, (7 ...
