On the growth of abnormal grains
Scripta Materialia, 1997This paper presents a contribution to the theory of abnormal grain growth in two dimensions by considering an idealized model with both a variable boundary energy and a variable mobility. The authors idealize the problem by considering a single A grain in a matrix of B grains where the AB boundary has a different energy and mobility from the BB ...

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.

Abstract 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. The similarity of the size and shape distributions facilitates the treatment of grain growth as a univariant statistical problem in ...

The growth of grain avalanches
Physica A: Statistical Mechanics and its Applications, 2002Abstract We bring out the salient characteristics displayed by grain avalanches in laboratory experiments. We devise then elementary mechanisms accounting for these main features and we derive a modeling capable of capturing the nonlocal processes relevant to the avalanche expansion.
