Abstract

An investigation is made of the change in expansion rate V of spiral dislocational half-loops in NaCl crystals after brief application of an electric field. It is established that, after the application of a field pulse at fixed shear stress, V rises sharply at first and then, with time, falls exponentially to its initial value. The initial increase in V depends on the amplitude of the electric pulse, and the relaxation time of its subsequent fall on the temperature. The activation energy of the process is determined from the temperature dependence of the relaxation time.
