Abstract
The thermal-mechanical fatigue behaviour of MA760, an oxide-dispersion strengthened superalloy was investigated using a temperature range from 550 °C to 1050 °C. Thermal-mechanical fatigue life was compared with low cycle fatigue life at 950 °C. Metallographic observations were used to study the initiation sites and paths of cracks and the stability of the γ′ strengthening phase.
