In particular, the low-energy ($0.5$ keV) ion-sputtering induced transient enhanced intermixing has been studied by MD simulations. {\\em Ab initio} density functional calculations have been used to check and reparametrize the employed heteronuclear interatomic potential. We find a robust intermixing in Pt/Ti driven by nanoscale mass-anisotropy .
