高温断裂力学的研究对于高温构件的设计,使用、安全评定有着重要的意义。本文综述了蠕变裂纹扩展研究的状况。概要介绍了蠕变裂纹扩展速率与一些力学参量(如应力强度因子K,净截面应力бnet C~*等)的关系,和温度、环境、损伤等因素对蠕变裂纹扩展性能的影响。 The research of high temperature fracture mechanics is of great significance to the design, use and safety assessment of high temperature components. This article reviews the status of creep crack growth research. The relationship between the creep crack growth rate and some mechanical parameters such as stress intensity factor K and net section stress бnet C ~ * is briefly introduced. The influences of temperature, environment and damage on the creep crack growth performance are also introduced.
