How Grain Growth Stops: A Mechanism for Grain-Growth Stagnation in Pure Materials
Science, 2010Taking the Rough with the Smooth Even with extensive annealing at high temperatures, most polycrystalline materials will not become a perfect single crystal, which would represent the thermodynamically preferred state. The stability of the polycrystalline state has been attributed to the presence of impurities that accumulate at ...

The Elimination of Grains and Grain Boundaries in Grain Growth
Interface Science, 1997The topological changes that occur during coarsening of 2D and 3Dcellular structures, such as polycrystals, areinvestigated. Particular attention is given to the elimination ofgrain boundaries and grains with more than the minimum number oftopological elements.

Annual Review of Materials Research, 1990
in the average crystal orientation and can even result in epitaxial films. It is therefore not surprising that grain growth can profoundly affect the mechanical, electrical, and chemical properties of thin films. In this article the mechanisms and modes of grain growth in thin films will be reviewed.

A thermodynamic view is taken to explain how inclusions and lattice strains (developed when adjacent grains have slightly different lattice parameters) can be used to control grain growth in advanced ceramics. Experimental data are presented for the cases where A12O3 inclusions are used to inhibit normal grain growth in cubic ZrO2, ZrO2 inclusions ...

Grain Growth in Sintered Uranium Dioxide: I, Equiaxed Grain Growth
Journal of the American Ceramic Society, 1962Grain growth was investigated in a UO 2 sinter of 94%) theoretical density over the temperature range 1555° to 2440°C. The results were in close, but not exact, agreement with a theoretical expression describing grain growth with a poly‐crystalline matrix.

Grain Boundary Motion During Anisotropic Grain Growth
1994The relation between the properties of polycrystalline materials (such as strength, effective diffusivity, electrical conductivity, etc.) and the grain size distribution has motivated many attempts to characterize and ultimately control crystalline dimension.

Grain growth in three dimensions depends on grain topology
Physical Review Letters, 1993While the growth rate of the average volume in a three-dimensional polycrystal is well understood, the growth rates of individual grains (which determine material properties through the topological and volume distributions) are not known. Using a three-dimensional Q-state Potts model simulation, I find that the average canonical growth rate of a grain ...

Philosophical Magazine, 1969
Abstract The two commonly used relations to describe isothermal grain growth in materials (dD/dt=KjDm and D = βtn , where D is the grain size, t growth time, and K, β, m and n are constants defined in the text) are considered and the correct grain growth equations consistent with the boundary conditions are derived.

The idea of sintering is to join particles together without melting them. We may, however, use an additive that does melt. The particles can be crystalline or amorphous: We can sinter glass marbles so long as we don’t melt them; of course, the particles need not be spheres. If we go to too high a temperature, the marbles also deform.
