Abstract

The compression-compression fatigue and fracture behaviors were studied on the Zr50Al10Cu37Pd3 bulk-metallic glasses (BMGs) under a load control, employing an electrohydraulic machine, at a frequency of 10 Hz (using a sinusoidal waveform) with an R ratio of 10, where R = σmin.max. (σmin. and σmax. are the applied minimum and maximum stresses, respectively). The obtained results were compared with those of the tension-tension fatigue tests. The life under the compression-compression fatigue was improved significantly. However the fatigue-endurance limits in two different stress states are comparable. The fracture morphology and the specimen surfaces were observed. The possible different fracture mechanisms under two kinds of stresses were discussed.
