TLDR
In this paper, a simple atomistic model for the calculation of the impurity drag has been developed: while the above theories assume a rather extended stress field of the grain boundary, this model considers the case that the stress field has only atomic dimensions.About:

The eastern Tonale fault zone: a ‘natural laboratory’ for crystal plastic deformation of quartz over a temperature range from 250 to 700 °C
TL;DR: In this paper, a temperature gradient from ∼250 to ∼700°C was determined across the Tonale fault zone using critical syn-kinematic mineral assemblages from the metasedimentary host rocks surrounding deformed quartz veins.

Dislocation creep regimes in quartz aggregates
Greg Hirth,Jan Tullis +1 more
TL;DR: In this paper, the authors used optical and TEM microscopy to identify three regimes of dislocation creep in experimentally deformed quartz aggregates, depending on the relative rates of grain boundary migration, dislocation climb and dislocation production.

Deformation-related recrystallization processes
Martyn R. Drury,János Urai +1 more
TL;DR: A unified framework for the description of recrystallization mechanisms is proposed in this paper, which can be divided into three main types: rotation mechanisms, migration mechanisms, and general mechanisms which involve both basic processes.

The double-edge effect of second-phase particles on the recrystallization behaviour and associated mechanical properties of metallic materials
TL;DR: In this article, a review article summarizes the recent progresses on the complex interaction between second-phase particles and recrystallization and the science behind them, and concludes that the double-edge effect of second phase particles on the behavior and mechanical properties of metallic materials is still far from being clear.

The Impurity‐Drag Effect in Grain Boundary Motion
TL;DR: In this paper, the drag on a grain boundary produced by an impurity atmosphere is examined in detail, and is found to depend on the velocity of the grain boundary relative to the diffusivity of the impurity and its interaction with the grain boundaries.
Journal ArticleDOI
A quantitative theory of grain-boundary motion and recrystallization in metals in the presence of impurities
TL;DR: In this paper, a quantitative atomistic theory of boundary migration was developed, where it is assumed that interaction forces exist between the foreign atoms and the boundary, increasing the concentration of foreign atoms in the boundary.

TL;DR: In 97% gewalzten Goldeinkristallen der Orientierung (110) wurde die Bewegung kunstlich eingebrachter Groswinkelgrenzen unter dem Einflus einer zeitlich konstanten treibenden Kraft bei Temperaturen zwischen 230 and 340°C verfolgt as discussed by the authors.
