The relationship between dislocations and disclinations
TLDR
In this paper, it was shown that both the torsion tensor as well as the Riemann-Christoffel curvature tensor are necessary in order to describe completely the closure failure associated with a Burgers circuit.Abstract:
The methods of differential geometry have been applied to the Burgers circuit taken about a wedge diaclination. It is shown that both the torsion tensor as well as the Riemann-Christoffel curvature tensor are necessary in order to describe completely the closure failure associated with such a circuit. In particular, both tensors measure the dislocation contribution associated with the disclination.read more

Atomic-Level Observation of Disclination Dipoles in Mechanically Milled, Nanocrystalline Fe
TL;DR: In this article, high-resolution transmission electron microscopy was used to directly reveal the individual dislocations that constitute partial disclination dipoles in nanocrystalline, body-centered cubic iron that had undergone severe plastic deformation by mechanical milling.

Direct dynamic atomic mechanisms of strain-induced grain rotation in nanocrystalline, textured, columnar-structured thin gold films
TL;DR: In this paper, a thin film tensile technique with in situ atomic-scale observations was developed to directly characterize the atomicscale plastic deformation mechanisms and fracture process of nanocrystalline gold thin films.

Synchrotron X-ray microdiffraction reveals rotational plastic deformation mechanisms in polycrystalline thin films
TL;DR: In this article, a disclination model of closed dislocation walls is proposed and the geometry of transformations corresponding to a Burgers circuit enclosing the multipole disclination configuration is investigated.

Theory of Disclinations: II. Continuous and Discrete Disclinations in Anisotropic Elasticity.
TL;DR: A general theory of stationary disclinations for a linearly elastic, infinitely extended, homogeneous body is developed and Anthony and Mura's approaches to disclination theory are clarified.
