TLDR
In this paper, the authors considered the rate of point defect emission and absorption at high angle grain boundaries in single phase materials by means of an (intrinsic) boundary dislocation model and found that the emission rate depends on the boundary structure and the applied stress and/or point defect supersaturation.About:

Defect-interface interactions
TL;DR: In this paper, the authors review the present understanding of defect-interface interactions in single-phase and two-phase metal and oxide nanocomposites, emphasizing how interface structure affects interactions with point, line, and planar defects.

Low temperature creep of nanocrystalline pure copper
TL;DR: In this paper, the authors investigated the tensile creep of nano-grained pure Cu with an average grain size of 30 nm prepared by electrodeposition technique and found that the steady state creep rate is proportional to the effective stress se(ss0), where s is the applied stress, and s0 is the threshold stress.

The Growth of Crystals and the Equilibrium Structure of their Surfaces
TL;DR: In this paper, it was shown that the rate of growth of a surface containing dislocations is proportional to the square of the supersaturation for low values and to the first power for high values of the latter.

The influence of grain boundaries on mechanical properties
TL;DR: The effect of interfaces on mechanical properties is considered in this paper, with emphasis on dislocation mechanisms and the atomic scale structure of boundaries, and Elastic and plastic compatibilities at boundaries are treated.

Boundary defects, and atomistic aspects of boundary sliding and diffusional creep
TL;DR: The behavior of atoms in a grain or phase boundary when the boundary slides (when the crystals which meet at the boundary suffer a relative shear displacement parallel to the boundary plane) and during diffusional creep is described in this article.
