Dynamics of clustering in a binary Lennard-Jones material

摘要

We have performed constant temperature two-dimensional molecular dynamics simulations of a binary Lennard-Jones material, representing an idealized metallic alloy or a material containing a specified fraction of an additive atomic species. Differences in the interatomic potentials between the atomic species can lead to clustering of the alloy atoms. An exponential distribution of cluster size is obtained as time approaches infinity. For sufficiently strong attractions the distribution of cluster sizes becomes nearly independent of the force and the attained maximum cluster size reaches a saturation level. [References: 16]
