In this article, the effects of different atomics growing orientations to mechanical properties of Cu/Ta nanofilms with a circle void defect under tension process are studied using molecular dynamics simulation. The stress-strain relationship, structural phase transformations, dislocation mechanism, and local stress concentration are examined. The results show that the Cu[100]/Ta[111] nanofilm exhibited the most excellent mechanical properties. The FCC structures are mainly transformed into HCP structures, and <112>, <110> dislocations occurred in Cu sections. The local stress concentrations are focused around the intersection regions between void defect and Cu/Ta interface.
