Kh. Kloos et al., BEHAVIOR OF GAS-TURBINE BLADE MATERIALS U NDER LONG-TERM CREEP-FATIGUE LOADING, Materialwissenschaft und Werkstofftechnik, 24(7), 1993, pp. 250-257
The long-term creep fatigue behaviour of the gas turbine blade materia
l 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 shorte
r 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 accum
ulation rule using two different methods.
