The weak-beam method of electron microscopy was used to study dissociated edge dislocations and faulted dipoles in nickel. Micrographs were compared with many-beam computed image profiles in order to deduce values for the dimensions of the defects, and these results were then used in conjunction with anisotropic elasticity theory to obtain the stacking-fault energy or an upper limit. It was concluded that the true value of stacking-fault energy was most likely to lie in the range of 120 to 130mJ/m2.
