Notes:
This paper describes phase field simulations of the rafting behavior of γ’ phase with asimple interfacial dislocation network model. The interfacial dislocation network model accounts forthe effect of the network on the lattice misfit between γ and γ’ phases and the subsequent raftingbehavior. The model is implemented into the phase field simulation to see the dependence of therafting behavior of γ’ phases on the interfacial dislocation network. Without the dislocation networkmodel, the amount of the rafting was negligibly small. On the other hand, with the dislocationnetwork model, the γ’ phases shows a large amount of rafting, which is in good agreement with theresults of the experimental observations. Therefore, the combination of the phase field method andthe simple interfacial dislocation network model developed in this work is appropriate for thesimulation of the rafting of γ’ phases
