摘要：
The cyclic fatigue behavior of two as-cast amorphous Zr41.25Ti13.75Ni10Cu12.5Be22.5 alloys was examined. Although both had identical compositions, the fatigue endurance strength (10(7) cycles) was higher for the alloy with less free volume, as determined by differential scanning calorimetry experiments. Such differences are believed to result from the processing cooling rates. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
