Precipitate Free Zones along Recrystallization Grain Boundaries during Creep in a Directionally Solidified Superalloy

Article Preview

Abstract:

Microstructural evolution of an experimental directionally solidified superalloy with local recrystallization during creep was studied. Precipitate free zones (PFZs) were formed along the recrystallization grain boundaries that are perpendicular to the applied stress. The formation mechanisms of PFZs and creep cracks associated with PFZs were discussed based on the experimental observation.
