The energy necessary to generate a dislocation is proportional to the square of the length of the Burgers vector, l b l2. This means that the most stable (lowest energy) dislocations have the minimum length lbl. For the BCC metal structure, calculate (relative to Eb=[111]) the dislocation energies for (a) Eb=[110] and (b) Eb=[100].
