The creep rupture strength of the cast alloy was similar to that of the wrought alloy, because such defects and segregations influencing the TS grew out of, or partially dissolved, during creep; thus, their effect was gradually eliminated.
(2) The creep rupture strength of the cast alloy exhibited no difference to that of the wrought alloy, because the inhomogeneous microstructure of the cast alloy between dendritic and interdendritic regions contained secondary particles that dissolved during long-term creep.
Using the creep rupture strength ([S.sub.c]) at the lime equivalent to the applied fatigue cycles, a relationship between mean stress and alternating stress was proposed as:
Such reduction in creep rupture strength promotes the fine grain cracks on the parent metal side of HAZ.
The detail at right shows that the 100,000 creep rupture strength decreases with increasing Ni content.
The observed substructural changes correlate well with creep rupture strength degradation and failure mode transition of creep-exposed CB2 welds studied in present investigation.
