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 ...

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.)

The Effect of He on the Evolution of Radiation-Induced Dislocation Loops near W/Cu Interface
MetalsIn the current work, the distribution behaviors of irradiation-induced dislocation loops near the W-Cu interface (contains a thin W2C transition layer) under self-interstitial atom diffusion-dominated conditions were investigated based on the comparative

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 ...

Topological Defects in Spin Density Waves
, 2000 The rich order parameter of Spin Density Waves allows for unusual object of a complex topological nature: a half-integer dislocation combined with a semi-vortex of a staggered magnetization. It becomes energetically preferable to ordinary dislocation due

A Brief Review of the Impact of Neutron Irradiation Damage in Tungsten and Its Alloys
MetalsNeutron irradiation poses a substantial challenge in the development and application of tungsten (W) and its alloys, predominantly in the framework of nuclear fusion and fission environments. Although W is well-acknowledged for its unique properties like

Light from Si via dislocation loops
Materials Today, 2005 We give a brief overview of the development and recent progress of a new technology, silicon dislocation-engineered light-emitting diodes (LEDs). The dislocation-engineering method enables the development of light emitters in conventional silicon technology.
