Abstract Scope |
Nickel-based superalloy Haynes 282 has been considered as one potential candidate material to be applied in advanced ultrasupercritical (AUSC) power system since the good oxidation resistance of this superalloy and stability of the oxidation phase as well as excellent strength at high temperature has been observed in recent years. The integrity of the oxidation layer is crucial to mitigate the oxidation, and this integrity would be altered the by the accumulation of residual stress in the oxide and the superalloy matrix. In this study, and the gravimetric analysis on Haynes 282 has been carried out in the temperature range from 800 to 950 C for 720 hours. Furthermore, the residual stress of oxide phases and the matrix been evaluated using X-ray diffraction method. The effect of residual stress with the high temperature oxidation on evolution of microstructure in this superalloy is discussed. |
