Strain-rate cycling tests associated with the oscillation were carried out at 80 to 240K for two kinds of single crystals: quenched and annealed specimens of KCl:Sr2+ (0.050 mol% in the melt). By examining the plots of the strain-rate sensitivity of flow stress and stress decrement, it was found that the effective stress, τp1 , due to impurities became obviously smaller at low temperature when I-V dipoles turned into the aggregates. The reason for a decrease in the effective stress was described in terms of the Fleischer’s model.
