✦ Synopsis

A cluster dynamics model has been parametrized to quantitatively reproduce results obtained by atomistic kinetic Monte Carlo (AKMC) modeling on the precipitation of Cu in a-Fe under thermal aging. The cluster mobility, highlighted by AKMC, is shown to have a significant effect on the precipitation kinetics and can reconcile the experimentally observed fast kinetics with the relatively low diffusivity of Cu monomers.

The soft deposition of copper clusters on the Au(0 0 1) surface is studied by constant temperature molecular dynamics simulations. The influence of the incident kinetic energy in the low-energy limit and of the temperature is analyzed. Deposition energies range from 1 to 100 meV/atom. The equilibriu
