Abstract

Molecular dynamics simulations are performed to investigate the plastic deformation of a gradient nano-grained (GNG) copper film. An extra strengthening is observed in the GNG film which indicates there is synergetic interaction between different grain-size layers. The plastic deformation of the GNG film occurs first in small grains and then propagates into larger grains with increasing strain. This orderly plastic deformation process is attributed to the GNG structure and found independent of strain rate and temperature. Grain coarsening induced by the deformation is apparently suppressed in the GNG film due to the GNG structure.
