Abstract
Double-faulted ribbons of stacking faults on the same {111} plane have been found in a L12 pseudobinary Ni3Ge- Fe3Ge compound. They stem from the interaction of coplanar <110> superdislocations giving rise to <112> dislocations, which subsequently dissociate into three identical <112> Shockley partials. It is shown that, provided that a larger core relaxation of the <112> partial dislocations is assumed, the threefold dissociated configuration has a lower energy than the antiphase-boundary dissociated configuration.
