TLDR
In this paper, the stresses round a circular prismatic dislocation loop are determined and used to calculate the spacings between such loops in a row generated from a source of internal stress.Abstract:
The stresses round a circular prismatic dislocation loop are determined and used to calculate the spacings between such loops in a row generated from a source of internal stress. The results are consistent with the available experimental observations.read more

Work hardening of dispersion-hardened crystals
TL;DR: In this article, a new theory of work hardening in dispersion-hardened single crystals is described, which is based on the fact that, if the particles do not deform plastically, and the interface between particle and matrix does not fracture, then secondary slip must occur locally round each particle when the crystal is deformed, even though the crystal may appear to deform by single slip.

The theory of diffuse X-ray scattering and its application to the study of point defects and their clusters
TL;DR: In this article, the theory of diffuse scattering by point defects and by defect clusters is reviewed, and the Huang scattering very near to the Bragg reflection increases in direct proportion to the number of point defects in the cluster.

Defects in silicon
TL;DR: In this paper, it is shown that polycrystalline silicon contains various impurities including oxygen, carbon, boron and possibly hydrogen, and the defects and impurities often show a nonhomogeneous distribution in the form of helical swirls.

Dislocations and stacking faults
J W Christian,V Vítek +1 more
TL;DR: A comprehensive introduction to dislocation theory for the physicist who is not a specialist in crystal plasticity is given in this article, with a survey of the established theory relating to the geometrical and topological properties of dislocations.

Neutron-irradiated molybdenum: relationship of microstructure to irradiation temperature.
J.L. Brimhall,B. Mastel +1 more
TL;DR: The microstructural defects produced in molybdenum by neutron irradiation in the temperature range 50 °C to 800 °C have been characterized by transmission electron microscopy as mentioned in this paper.

Observations on helical dislocations in crystals of silver chloride
D. A. Jones,J. W. Mitchell +1 more
TL;DR: In this paper, the authors described the properties of prismatio and concentric helical prismatic dislocations generated by the stress field which appears around a spherical glass inclusion in a silver chloride crystal when the crystal is cooled from a temperature of 370°c to room temperature.

Speculations on the Properties of the Silver Halide Crystals
TL;DR: In this paper, the Gurney-Mott theory of photolytic action was extended to the case of pure silver halides, and it was suggested that the addition of sulfur to the halides plays a role in enhancing darkenability in three ways: (a) by forming precipitates which produce distortion that enhances the number of incipient vacancies, (b) by extending the absorption spectrum toward the red end of the spectrum; and (c) by increasing the equilibrium density of interstitial silver ions.

Some properties of crystals of silver chloride containing traces of copper chlorides
TL;DR: In this paper, it was shown that the space required for the separation of further silver atoms upon a silver particle inside the crystal is made available by the formation of prismatic dislocation loops which glide away from the interface between the particle and the surrounding crystal.
