| 摘要 | A detailed reliability analysis of a series of Zr-based bulk metallic glasses (BMGs) was conducted using three-parameter Weibull model. In particular, the location parameter of the three-parameter Weibull was used to characterize the presence of critical failure-free stress, i.e. the stress below which there is no failure. Such characterization results in almost identical estimates for the Weibull modulus of these BMGs, indicating that their failure mechanism is the same. The three-parameter Weibull model thus provides a more interpretable and accurate reliability assessment of BMGs. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd.
