TLDR
In this paper, the difficulty for a second-phase particle to pinch off when the grain boundary migrates, affects the final grain size, and theoretical models for this effect are discussed.About:

Mechanisms for microstructure evolution in electroplated copper thin films near room temperature
James Mckell Edwin Harper,C. Cabral,Panayotis C. Andricacos,Lynne Gignac,Ismail C. Noyan,Kenneth P. Rodbell,Chao-Kun Hu +6 more
TL;DR: In this paper, a model based on grain boundary energy in the fine-grained as-deposited films providing the underlying energy density which drives abnormal grain growth is presented.
Journal ArticleDOI
Plate tectonics, damage and inheritance
David Bercovici,Yanick Ricard +1 more
TL;DR: Bercovici and Ricard as discussed by the authors showed that when sufficient lithospheric damage accumulates, the theory states, shear-localization occurs and long-lived weak zones develop.

Grain Structure Control of Additively Manufactured Metallic Materials.
TL;DR: In this paper, the authors summarized methods to promote fine equiaxed grains in both the additive manufacturing process and subsequent heat treatment and discussed the influence of temperature gradient, solidification velocity and alloy composition on grain morphology.
Journal ArticleDOI
Mechanisms for the generation of plate tectonics by two-phase grain-damage and pinning
David Bercovici,Yanick Ricard +1 more
TL;DR: In this paper, the authors present a theoretical model for the mechanism of lithospheric weakening and shear-localization and hence plate generation through damage, grain evolution and Zener pinning.

How Grain Growth Stops: A Mechanism for Grain-Growth Stagnation in Pure Materials
TL;DR: It is concluded that grain-boundary roughening provides an alternate stagnation mechanism that applies even to high-purity materials, and thus pin the polycrystalline structure, even in the absence of impurities.

On the theory of normal and abnormal grain growth
TL;DR: In this article, a growth equation for individual grains in single-phase materials is suggested, which is used to calculate a rate equation for normal grain growth and the size distribution in the material.
Journal ArticleDOI
Computer simulation of grain growth—I. Kinetics
TL;DR: In this paper, a Monte Carlo procedure is applied to the study of grain growth in two dimensions, where the initial distribution of orientations is chosen at random and the system evolves so as to reduce the number of nearest neighbor pairs of unlike crystallographic orientation.

On the Zener drag
E. Nes,N. Ryum,O. Hunderi +2 more
TL;DR: In this article, both the relatively simple problem of the interaction between a single particle and a grain boundary, and the much more complicated problem of deriving a restraining force from the many particles on the grain boundary have been considered.
Journal ArticleDOI
Computer simulation of grain growth—V. Abnormal grain growth
TL;DR: In this paper, the growth of abnormally large grains is modelled under two conditions: 1) where the driving force is provided solely by curvature and 2.1 where the difference in the gas-metal surface energy between grains of different crystallographic orientation.

Computer simulation of grain growth-III. Influence of a particle dispersion
TL;DR: In this paper, a Monte Carlo computer simulation technique has been developed which models grain growth in the presence of a particle dispersion, allowing for the monitoring of an evolving microstructure as a function of time.
