Intermittent serrated flows of a ductile bulk metallic glass (BMG) at different strain rates is investigated by statistic analysis of stress drops during plastic flows. The scaling behavior, i.e. a complementary cumulative distribution function (CCDF) is predicted universally by simple but wisdom mean-field model (MFT). The remarkable agreement between the measured slip-avalanche magnitudes and MFT prediction indicates that the plasticity for the present Fe-based BMGs can be tuned by imposed strain rates. In addition, this tuned plasticity is illuminated with the free-volume model.
