Interaction between the edge dislocation dipole pair and interfacial misfit dislocation network in Ni-based single crystal superalloys

Understanding the intrinsic strengthening mechanism is of great significance for microstructural design Ni-based single crystal superalloys. In this paper, from an atomistic perspective, interacting between edge dislocation dipole pair and interfacial misfit network has been elaborated. It shown that a dislocations can effectively impede movement matrix dislocations, accommodate pile up pairs in Ni matrix. Furthermore, we have systematically elucidated influence loading rates on stimulating period stiffness Ni/Ni3Al substrate. These findings provide better understanding
