A series of simulated microstructures containing nanometer-scale precipitates was created with an atom probe data simulator. These data were then analyzed with the proximity histogram by creating isoconcentration surfaces to determine the influence of the analysis method. For simulated 2-nm-radius spherical precipitates, the optimized voxel size and delocalization were found to be 0.5-0.6 nm and 1.0-1.5 nm, respectively. Under optimum analysis parameters, the voxelization/delocalization process only slightly degrades the interface width determined from the proximity histogram to ∼0.15±0.04 nm.
