Simulation of copper nanocrystal plastic deformation at uniaxial tension

Abstract

Computer simulation of plastic deformation of FCC copper nanocrystal in the process of uniaxial tension in a direction [001] is performed by methods of molecular dynamics and a static relaxation. It is shown that thermoelastic martensite transformation is responsible for plastic deformation, FCC lattice is reconstructed into HCP lattice. Orientation relationship of contacting phases is identified.
