Abstract
Stacking fault shearing is commonly observed in Co-base and CoNi-base superalloys in the intermediate temperature regime between 850 °C to 1000 °C in contrast to Ni-base superalloys. In this work, we report on the significance of recovery processes after aging and creep experiments on predeformed specimens with extreme stacking fault densities. Above 950 °C, superlattice stacking faults start to recover rapidly, whereby intrinsic ones recover more quickly than extrinsic ones. Our results also reveal that the significance of stacking fault shearing in the high temperature creep regime could be higher than that indicated by traditional postmortem investigations due to recovery processes.
