Strain-rate cycling tests associated with the oscillation were carried out at 80 to 240K for two kindsof single crystals: quenched and annealed specimens of KCl:Sr^2+ (0.050 mol% in the melt). By examiningthe plots of the strain-rate sensitivity of flow stress and stress decrement, it was found that the effectivestress, τ_p1, due to impurities became obviously smaller at low temperature when I-V dipoles turnedinto the aggregates. The reason for a decrease in the effective stress was described in terms of theFleischer's model.
