Charged dislocations and plasto-electric effect in ionic crystals

The electric charges on the edge dislocations in KCl single crystals doped with divalent cation impurities were determined as a function of impurity concentration and temperature. This is then used to determine the density of mobile dislocations in compression, strain rate cycling, stress relaxation, latent hardening and the Bauschinger effect by using the plasto-electric effect. Some other plasto-electric, electro-plastic and magneto-plastic effects are also discussed.
