Abstract
The ‘weak-beam’ technique of Cockayne, Ray and Whelan (1969) for resolving very closely spaced dislocations in the electron microscope has been applied to the dissociation of BZ-type superlattice dislocations in highly ordered Fe-35 at. % Al. By plotting the separation of the partials as a function of orientation a value of 105±15 erg om−2 has been obtained for the antiphase boundary energy.Keywords
