The atomic mechanisms of plastic deformation near the Ni-Al, Cu-Au, Ni-Fe
coherent interphase boundaries in two-dimensional model are studied by the method of
molecular dynamics. It is shown that plastic deformation near the interphase boundary is
closely connected with misfit dislocations. Plastic shears and destruction of the bimetals are
initiated near the misfit dislocations cores.
Keywords: two-dimensional bimetallic systems; the interphase boundary; plastic deformation; molecular dynamics study
