Abstract
A refined analysis of dislocation energy and dislocation networks in {110} planes of α‐iron crystals is presented on the basis of anisotropic elasticity. Contrary to the conclusions given by isotropic theory, the elastic energy per unit length of a screw segment, with Burgers vector a〈100〉, is greater than that of an edge segment with the same Burgers vector lying in a {110} plane. The latter in turn is greater than the sum of the energies of two screw segments with Burgers vector (a/2)〈111〉. The shape of a stable net composed of a〈100〉 screw segments and (a/2)〈111〉 segments of mixed character in {110} planes is determined by the line tension method. Comparison between theory and experiment is discussed. It is shown that the anisotropic theory agrees well with the observations.This publication has 13 references indexed in Scilit:
