| Abstract Scope |
The tendencies for preferred contact among grains of different numbers of faces is quantified using an affinity term describing the actual frequency of occurrence of grain pairs relative to the frequency expected from random contact. Thus, the affinity term describes these tendencies as multiplicative factors of occurrence greater or less than the random state. Data from 3D Monte Carlo simulations shows preferred contact between grains with high and low numbers of faces, with affinities as high as 8 times random. Mid-class grains of approximately 14 faces show merely random contact, i.e., no preference or avoidance, with grains of higher and lower numbers of faces. Affinities also have been determined for different topological characteristics on separated grains. These affinity characteristics provide insight into the topological mechanism of grain growth. |
