Abstract
Examination, by transmission electron microscopy, of a deformed Ni 70 at. % Co alloy has shown that, although all glide faults examined were intrinsic, extended extrinsic nodes and intrinsic-extrinsic stacking-fault bends occur. However, none of the stacking-fault tetrahedra formed during deformation was found to be extrinsic. From these results it is deduced that the extrinsic stacking-fault energy is considerably greater than the intrinsic stacking-fault energy, and it is suggested that the shape of the extrinsic nodes may be determined by the high value of the extrinsic stacking-fault energy.Keywords
