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.

Keywords: martensite transformation, deformation, computer simulation, molecular dynamics, nanocrystal, uniaxial tension.
