The effect of added oversized elements on the microstructure of binary alloy nanoparticles.

Molecular dynamics simulations are used to investigate the microstructures of Cu-Ni nanoparticles with different concentrations of oversized atoms added to them. A many body second moment tight binding approximation potential is adopted to model the interatomic interactions. The Honeycutt-Anderson (HA) pair analysis technique is adopted to analyse in detail the transformation between local structures at different temperatures.
