Facilitating effect of interfacial grooves on the rafting of nickel-based single crystal superalloy at high temperature

Interfacial grooving induced by dislocation stress takes place at γ/γ′ interfaces during creep and aging of a third-generation nickel-based single crystal superalloy at 1120 °C. At the tip of grooves, γ′ phase is directly measured under compressive stress of interfacial dislocations, which likely dr...

520			\|a Interfacial grooving induced by dislocation stress takes place at γ/γ′ interfaces during creep and aging of a third-generation nickel-based single crystal superalloy at 1120 °C. At the tip of grooves, γ′ phase is directly measured under compressive stress of interfacial dislocations, which likely drives the γ′-forming elements out. The enrichment of Re and Co elements are detected in the tip. Meanwhile, γ′ precipitates coarsen much faster when more grooves form at the interfaces along the coarsening direction. This suggests that interfacial grooves facilitate the rafting of γ′ precipitates, especially under the creep stress.

At the tip of grooves, γ′ phase is directly measured under compressive stress of interfacial dislocations, which likely drives the γ′-forming elements out. The enrichment of Re and Co elements are detected in the tip. Meanwhile, γ′ precipitates coarsen much faster when more grooves form at the interfaces along the coarsening direction. This suggests that interfacial grooves facilitate the rafting of γ′ precipitates, especially under the creep stress.

abstract	Interfacial grooving induced by dislocation stress takes place at γ/γ′ interfaces during creep and aging of a third-generation nickel-based single crystal superalloy at 1120 °C. At the tip of grooves, γ′ phase is directly measured under compressive stress of interfacial dislocations, which likely drives the γ′-forming elements out. The enrichment of Re and Co elements are detected in the tip. Meanwhile, γ′ precipitates coarsen much faster when more grooves form at the interfaces along the coarsening direction. This suggests that interfacial grooves facilitate the rafting of γ′ precipitates, especially under the creep stress.
