摘要：

High temperature creep damage and fracture are discussed. The expressions of the stress intensity factor threshold and initiation time are obtained under given conditions. The range of applicability of the characterizing parameter for creep crack growth is analysed on the basis of fracture mechanics and determined under certain conditions. The influence of temperature on creep crack growth rate is analysed, and the expressions for creep crack growth rate are obtained.
