TLDR
In this paper, the authors extended the classical theory of the coarsening of precipitate particles by competitive growth to include the effect of encounters between growing particles using the method outlined by Lifshitz and Slyosov [J. phys. solids19, 35 (1961)].About:

The Theory of Ostwald Ripening
TL;DR: In this paper, the role of elastic fields during Ostwald ripening in solid-solid mixtures is reviewed, and it is shown that these fields can play a dominant role in determining the coarsening behavior of a solid solid system.
Journal ArticleDOI
Review: liquid phase sintering
TL;DR: A review of the literature on liquid phase sintering can be found in this paper, with a focus on the densification and microstructure evolution events of a mixture of powders.

Review Progress in Ostwald ripening theories and their applications to nickel-base superalloys Part I: Ostwald ripening theories
TL;DR: A detailed review of the physical basis behind the second phase coarsening process for two-phase mixture has been reviewed in detail, using the various theories developed to describe this process as discussed by the authors.

Liquid immiscible alloys
Lorenz Ratke,S. Diefenbach +1 more
TL;DR: In this article, the authors describe the extensive progress that has been made during the last decade and also the fundamentals of immiscibles and also show that the combination of classical laboratory research, research under reduced gravity conditions and a newly developed computational modelling technique seems to be just becoming available to solve the problems of decomposition, spatial phase separation and microstructure evolution during cooling of an alloy through the liquid miscibility gap.

The kinetics of precipitation from supersaturated solid solutions
I.M. Lifshitz,V.V. Slyozov +1 more
TL;DR: In this paper, an analysis is made of the process whereby diffusion effects can cause the precipitation of grains of a second phase in a supersaturated solid solution, and the kinetics of this type of grain growth are examined in detail.

Morphological Stability of a Particle Growing by Diffusion or Heat Flow
W. W. Mullins,R. F. Sekerka +1 more
TL;DR: In this article, the stability of the shape of a phase boundary enclosing a particle whose growth during a phase transformation is regulated by the diffusion of material or the flow of heat is studied.

Theory of Growth of Spherical Precipitates from Solid Solution
TL;DR: In this paper, the radius of a spherical precipitate particle growing in a solid solution of initially uniform composition was shown to be equal to α(Dt)½, where D is the atomic diffusion coefficient, t the time of growth, and α, the growth coefficient, is a dimensionless function of the pertinent compositions.
Journal ArticleDOI
The effect of volume fraction on particle coarsening: theoretical considerations
TL;DR: In this paper, the authors modified the theory of diffusion-controlled particle coarsening developed by Lifshitz and Slyozov and Wagner (LSW) to take into account the volume fraction, φ, of precipitate.

On the modulated structure of aged Ni-Al alloys: with an Appendix On the elastic interaction between inclusions by J. D. Eshelby
Alan J. Ardell,R.B Nicholson +1 more
TL;DR: In this paper, it is shown that there exists an elastic interaction between the Ni-6.71 wt.% Al alloy particles arising from the difference between the elastic moduli in the precipitate and the matrix.
