Micro-Scale Mechanical Behavior of Ultrafine-Grained Materials Processed by High-Pressure Torsion
TL;DR: In this paper, the development of micro-mechanical behavior is observed after significant changes in microstructure through high-pressure torsion (HPT) processing of bulk ultrafine-grained (UFG) materials usually show superior mechanical and physical properties.
Book ChapterDOI
Applying conventional creep mechanisms to ultrafine-grained materials
TL;DR: In this article, the authors examined the applicability of these flow processes in new and advanced materials with ultrafine grain sizes, by initially reviewing the fundamental mechanisms occurring in high temperature creep and then considering the extension of this approach to materials having ultra fine grain sizes.

Diffusional Viscosity of a Polycrystalline Solid
TL;DR: In this article, it is suggested that mosaic boundaries and boundaries between grains of nearly the same orientation may not serve as sources or sinks of the diffusion currents, in which case the creep rate will depend only on the configuration of grain boundaries having a sizable orientation differen...
