摘要：
The long-term creep fatigue behaviour of the gas turbine blade material IN-738 LC HIP is investigated by a service-type strain cycle up to a test duration of about 12 000 h. Further, it is reported about shorter tests of the same type on alloy IN-100 HIP The cyclic deformation of alloy IN-738 LC HIP in the long-term region is analysed and the creep fatigue crack initiation is described by the generalized damage accumulation rule using two different methods.
