Strain-rate cycling tests during the Blaha effect measurement were carried out at 80 to 240K for two kinds of single crystals: quenched and stored specimens of KCl:Sr2+ (0.050 mol% in the melt). The plots of the strain-rate sensitivity of flow stress and stress decrement had two bending points and two plateau places for both the specimens. On the basis of the relative curve of strain-rate sensitivity and stress decrement, it was found that the effective stress due to impurities for the stored specimen is smaller than that for the quenched specimen within the temperature.
