Abstract

The nature of dislocation contrast in field ion micrographs is examined and it is shown that spirals should be observed in most orientations. This analysis is extended to the spiral structures observed at boundaries and evidence for dislocations at a low angle boundary, a noncoherent twin, and a random boundary is presented in the context of lattice coincidence.
