A definition of the self-stress of a dislocation was proposed which was closely related to the more usual notion of line tension. The definition permitted a numerical calculation to be made of the shape of extended nodes in dislocation networks, and such calculations led to revised values of the stacking-fault energies of alloys. It was found that (to within the usual scatter) the values of stacking-fault energy deduced by Howie and Swann (1961) had to multiplied by 2.3, giving a revised value of 345mJ/m2.
