Effect of aspect ratio on the serrated flow behavior of Zr61.7Al8Ni13Cu17Sn0.3 bulk metallic glass

The serrated flow behavior of Zr61.7Al8Ni13Cu17Sn0.3 bulk metallic glass with different aspect ratios was investigated. For the samples with aspect ratios below 2.0, the serrated flow behavior changes from uniform to nonuniform with increasing aspect ratios. The histograms of normalized stress drop magnitude all exhibit a peak shape and the mean stress drop magnitude increases with increasing aspect ratios. The serrated flow behavior is special...
