Abstract
The weak-beam technique of electron microscopy (Cockayne, Ray and Whelan 1969) has been used to image the fourfold dissociation of superlattice dislocations in a DO3-ordered Fe-26 at.% Al alloy. Values of 77±12 and 85±16 erg cm-2 have been obtained for the first and second nearest-neighbour antiphase boundary energies, respectively.Keywords
