NaCl単結晶の転位の運ぶ電流と応力緩和

抄録

Electric current carried by edge dislocations during the stress relaxation of NaCl single crystal was measured at room temperature. It was found that the current was proportional to the stress relaxation rate if the sample was strained less than about 1.3%. The inverse of current increased linearly with time at the beginning of stress relaxation. This is in accord with the results obtained by Ohring et al. for LiF and KCl single crystals. The fraction of charged dislocations, f, moving in the direction of the observed current is considered to decrease for large strains.
