Abstract
The micro-mechanisms involved in the γ/γ′ rafted microstructure built up at 1050°C in <001> oriented MC2 superalloy single crystals were analyzed. The analysis was performed by means of scanning electron microscopy (SEM), post mortem and in situ transmission electron microscopy (TEM). It was found that the creation and propagation modes of moving dislocations evidenced the important role of the misfit dislocation network as well as strength of the γ/γ′ interfaces.
