Large scale atomistic simulations of screw dislocation structure, annihilation and cross-slip in FCC Ni
Using QM-Sutton-Chen many-body potential, we have studied the 1/2a〈1 1 0〉 screw dislocation in nickel (Ni) via molecular dynamics (MD) simulations. We have studied core energy and structure using a quadrupolar dislocation system with 3D periodic boundary conditions. The relaxed structures show dissociation into two partials on {1 1 1} planes. The equilibrium separation distance between the two ...
متن کاملFine Cross-slip of a Screw Dislocation in Anti-plane Shear
In this work we present the main results of Armano and Cermelli [1] regarding the motion of a screw dislocation in a crystalline solid. It is well known that dislocations can only move along a finite number of crystallographic directions: in two dimensions, the resulting trajectories are piecewise rectilinear paths. However, in special situations such as near an attractor, dislocations are forc...
متن کاملSpontaneous athermal cross-slip nucleation at screw dislocation intersections in FCC metals and L12 intermetallics investigated via atomistic simulations
In this manuscript, we extend on our prior work to show that under certain conditions cross-slip nucleation is athermal and spontaneous with zero activation energy in FCC elemental metals such as Ni and Cu, and L12 intermetallic compounds such as Ni3Al. Using atomistic simulations (molecular statics), we show that spontaneous cross-slip occurs at mildly repulsive intersections. Further, the loc...
متن کاملMicrostructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals
Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial disloc...
متن کاملAnalysis of size-dependent slip transfer and inter-twin flow stress in a nanotwinned fcc metal
Nanotwinned structures offer the potential to effectively enhance strength while preserving ductility and damage tolerance. In this paper we present an analytical model for quantifying slip transfer across twin boundaries and for deriving the attendant flow stress as a function of the twin lamellae size in nanotwinned face-centered cubic metals. The mechanistic models investigate how single or ...
