TLDR
In this paper, a statistical approach has been applied to particle coarsening during liquid phase sintering assuming direct particle coalescence as basic growth mechanism instead of Ostwald ripening.About:

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.
Journal ArticleDOI
Semisolid metal processing
TL;DR: Semisolid metal (SSM) processing is a relatively new technology for metal forming as discussed by the authors, which deals with semisolid slurries, in which non-dendritic solid particles are dispersed in a liquid matrix.

Evolution of near-equiaxed microstructure in the semisolid state
TL;DR: In this paper, the microstructure of alloys with a near-equiaxed micro-structure, produced by spray casting, magnetohydrodynamic (MHD) casting and the stress induced, melt activated (SIMA) process, as it evolves within short times in the semisolid state, is examined by rapid quenching and isothermal soaking experiments.

Coarsening in Sintering: Grain Shape Distribution, Grain Size Distribution, and Grain Growth Kinetics in Solid-Pore Systems
TL;DR: Sintering occurs when packed particles are heated to a temperature where there is sufficient atomic motion to grow bonds between the particles as mentioned in this paper, and the conditions that induce sintering depend on the material, its melting temperature, particle size, and a host of processing variables.

Microstructural evolution during partial remelting of AlSi7Mg alloys
W.R. Loué,M. Suéry +1 more
TL;DR: In this article, a shape factor capable of a realistic description of the microstructural evolution is introduced, which is used to describe the influence of initial solidification conditions (like electromagnetic stirring, solidification time, modification of the eutectic and grain refinement) and thermomechanical treatments prior to partial remelting (like solutionizing and cold rolling).

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.
Journal ArticleDOI
Effect of Change of Scale on Sintering Phenomena
TL;DR: In this paper, it is shown that when certain plausible assumptions are fulfilled simple scaling laws govern the times required to produce, by sintering at a given temperature, geometrically similar changes in two or more systems of solid particles.
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.

The dependence of ostwald ripening kinetics on particle volume fraction
A.D. Brailsford,Paul Wynblatt +1 more
TL;DR: In this paper, a spatially homogeneous rate theory was developed to describe the time rate of change of the radius of a spherical particle embedded in a configurationally random array of particles of like nature but differing sizes.
