摘要：

Practical experience of creep failure of components in service is discussed in relation to the creep rupture properties of HK40 (25Cr-20Ni-0.4C) and HP40 (25Cr-35Ni), which are considered using traditional and new data analysis procedures. The new approach is shown to offer not only a sensible mechanistic interpretation of the observed behaviour patterns but also a reasonable method for predicting long-term fracture strengths by extrapolation of short term creep life values.
