Abstract
A statistical calculation is carried out for the energy change due to the passage of dislocations having different Burgers vectors across equilibrium and nonequilibrium antiphase boundaries (APB) of various crystallographic orientations in stoichiometric B2 and Ll2 superstructures. The passage of the first superdislocation is shown to be accompanied by an energy change which depends on the relative orientation of the APB displacement vector and the superdislocation Burgers vector. The temperature dependence is obtained for the energy change accompanying the passage of a superdislocation across equilibrium and nonequilibrium APB's.
