摘要：

The electric charges on the edge dislocations in KCI 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. (C) 2000 Elsevier Science S.A. All rights reserved.
