TLDR
In this paper, the statistical approach to the problem of grain growth was used to study the process in material without texture and it was found that the present theories of normal grain growth do not give an adequate description of the process as they fail to take into account the effects of retarding force and the texture of material.About:

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.
Journal ArticleDOI
Overview no. 65
TL;DR: In this article, the development of theories for normal grain growth in pure single phase systems is reviewed and a major theme which emerges is the interplay between the topological requirements for space filling and the kinetics of change in mean grain size with time.
Journal ArticleDOI
Computer simulation of normal grain growth in three dimensions
TL;DR: In this paper, the microstructure of polycrystalline materials is digitized by dividing the polycrystaline material into small volume elements and storing the spatial location and crystallographic orientation of each element.

On a stochastic theory of grain growth
TL;DR: In this article, a theory of isothermal grain growth in polycrystalline solids, which treats grain growth as a statistical or stochastic process, is presented, where the noise or fluctuations are used to model the effect of complex topologically connected structure of the specimen on grain boundary motion, in addition to such motion directed by surface tension forces.

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.

The effect of thermal grooving on grain boundary motion
TL;DR: In this article, a theory is presented which describes the dynamics of thermal groove formation at a moving grain boundary, based on the Gibbs-Thompson formula relating curvature to chemical potential, and assumes surface diffusion to be the mechanism of groove development.

Grain growth in metals
TL;DR: In this paper, the sizes and shapes of grains in annealed metals, characterised respectively by the grain diameters and the interfacial angles, are shown to be lognormally distributed in planar sections as well as in space.

Activation energies for normal grain growth in lead and cadmium base alloy
TL;DR: In this paper, high temperature third and fourth stage grain growth has been found to conform to the theoretical rate equation, where the activation energy for third stage growth is considerably larger and is comparable to that of volume self-diffusion.
