Abstract Scope |
We report atomistic simulation studies of grain boundary structure, diffusion and deformation response in FCC materials. The simulations are based on empirical interatomic potentials and use massively parallel molecular dynamics techniques at the atomistic level. The studies address a series of grain boundaries with random misorientations around the [110] crystallographic axis. We analyze the relaxed structures using various models and visualization techniques including the dislocation content of the boundary region. We find that that the random boundaries contain a varying amount and types of dislocations as part of the structure. These in turn influence the deformation response and the diffusion properties of the boundaries. |
