摘要：

We respond to comments made regarding the large discrepancies in the high cycle fatigue life of a Zr-based bulk metallic glass when measured using four-point bending and notched tensile rod configurations. We reiterate our initial conclusions that the present of strong stress gradients and reduced stress at the fatigue initiation site together with the reduced sampling volume of the notched tensile rod experiments are the reasons for the large reported differences. Further stress life results measured using uniaxial tensile specimens are reported that are consistent with data from the four-point bending specimens. (c) 2007 Acta Materialia Inc.
