摘要：A "service condition-creep rupture property" interference model (SCRI model for short) based on Z parameter method is proposed to predict the reliability of creep rupture life for high temperature components. The dispersibility of creep rupture property and the fluctuation of service conditions such as servicing temperature and stress are considered in this model. The scattering of creep rupture data is generally supported by normal distribution. Monte-Carlo method is applied to evaluate the reliability at a certain operating condition by simulating the fluctuation of service temperature and stress. HK40 steel has been used as an example to demonstrate the influence of creep rupture property dispersibility and operating condition fluctuation on the result of reliability evaluation.
