Fig. 7. Schematic diagrams of dislocations slipping and decomposing on different planes of γ′ phase in the alloy during creep: (a) decomposition of dislocation on (11 1 ? ) plane to form SISF, (b) slipping and decomposing of dislocation on (11 1 ? ) plane, and (c) cross-slipping of dislocations from {111} to {100} planes to form K-W locks.
