Abstract:The plastic deformation mechanisms of Ni/Al2O3 interface systems under tensile loading at high strain rates were investigated by the classical molecular dynamics (MD) method. A Rahman–Stillinger–Lemberg potential was used for modeling the interaction between Ni and Al atoms and between Ni and O atoms at the interface. To explore the dislocation nucleation and propagation mechanisms during interface tensile failure, two kinds of interface structures corresponding to the terminating Ni layer as buckling layer (T… Show more
“…The results reveal that the fracture behavior and dislocation nucleation and propagation mechanisms are dependent on the interface structure, with Type II interfaces exhibiting higher yield strength due to more stable Ni-O bonds. This study provides insights into the deformation mechanisms of Ni/Al 2 O 3 interfaces under extreme conditions, aiding in the understanding of complex interface dislocation structures and their behavior [16].…”
