Abstract
Single crystal nickel-base superalloys, which are widely used in high-temperature structural applications have been developed with the aim of optimising creep resistance at elevated temperatures. Due to this, creep failure in aero-engine turbine blades is nowadays a rare event, and they are most likely to fail via a fatigue-based mechanism. In service conditions these components are exposed to cyclic changes in stress and temperature, which are best simulated in the laboratory by the so-called thermomechanical fatigue (TMF) test. In recent years, much effort has been devoted to the study of precipitate morphology under creep conditions [1,2], as it has an influence on the mechanical performance. A similar analysis of the changes in precipitate structure which develop under TMF is also highly relevant.
