摘要: Abstract Uniaxial tensile processes of nano-scale bilayer Cu/Ni with coherent interface (CI) and semi-coherent (SCI) are simulated by molecular dynamics (MD). The results show that in the deformation two kind structures, dislocations nucleate from leading slipping cross cause structures getting into plastic stage. SCI leads to strength strain rate sensitivity (SRS) depending on thickness Cu/Ni, because hindering slipping. However, due weak barriers CI, dislocation can easily, which independent SRS values thickness.
