It is shown that the characteristic slip directions and planes in metal crystals can be explained and predicted by taking into account the dependence of the energy of a dislocation on its plane. The energy of a dislocation is considered as a function of the parameter β , which is defined as the ratio of the Burgers vector to the interplanar spacing, and it is shown that the observed slip systems correspond to the lowest possible values of β in all the crystal types that have been studied. The reason for the existence of alternative slip systems, particularly at high temperatures, is also discussed in terms of this concept.
