The Effect of Strong Electric Field on Microhardness and Mobility of the Indented Dislocations in Alkali Halides

Abstract

Abstract Some regularities and particular specialties of electromechanical effect have been investigated in NaCI single crystals. The conclusion has been drawn that the existence of the electromechanical effect in crystals with ionic interatomic bonds appears to result from both the direct electrical field's force on charged dislocations, as the filaments and the modification under field influence the impurities, and point defect's state in the crystal lattice. The last modification is to vary the interactions between the obstacles and the dislocations moving in solid, thus facilitating or hardening the microplastic deformation in the hole.
