Extended Dislocations in Plastically Deformed Metallic Nanoparticles

In the present study, the sawtooth nature of compressive loading of metallic nanoparticles is observed using a molecular dynamics simulation. The atomic structure evolution confirmed that extended dislocations are the main defects split into two asynchronous partial disloca‐ tions, along with stored...

description In the present study, the sawtooth nature of compressive loading of metallic nanoparticles is observed using a molecular dynamics simulation. The atomic structure evolution confirmed that extended dislocations are the main defects split into two asynchronous partial disloca‐ tions, along with stored and released fault energy. This is considered the essence of sawtooth loading. The size of the nanoparticles relative to the equilibrium width of the extended dislocation is discussed to explain the simulation results.
