As a series study of the discrete dislocation dynamics (DDD) simulation on the interfacial dislocation network in Ni-based superalloys, we have performed various DDD simulations on the stability of dislocation network and its interaction with a prismatic dislocation loop. Dislocations cannot keep its network shape if the line and Burgers vectors are set to the experimental observation, while we can actually obtain stable networks with the vectors and slip plane reported in molecular dynamics (MD) simulations. Then we bump a prismatic dislocation loop into the networks, showing that a mesh knot is replaced by the prismatic loop as reported in our previous MD simulation. The interaction can be explained by the junction formation between the network and prismatic loop, so that we can conclude that any special modeling is not necessary for this interaction between the network and prismatic loop. © 2008 Elsevier B.V.
