Aluminium diffusion in decagonal Al-Ni-Co and Al-Cu-Co quasicrystals is investigated by molecular dynamics simulations. Results obtained with newly developed EAM potentials are compared to previous work with effective pair potentials [Phys. Rev. Lett. 93, 075901 (2004)]. With both types of potential, strong aluminium diffusion is observed above two thirds(More)
An introduction is presented to numerical methods, by which the behavior of complex metallic alloys can be simulated. We primarily consider the molecular dynamics (MD) technique as implemented in our software package IMD, where Newton's equations of motion are solved for all atoms in a solid. After a short discourse on integration algorithms, some possible(More)
