Morphology of γ′-Phase in Ni-Al Superalloy at High-Temperature Annealing

Abstract:

Phase composition and γ′-phase morphology of a superalloy on based N I-Al doped by high-melting elements in it after ordering annealing hawe been studied by TEM, SEM and electron microdiffraction methods. It is revealed that after annealing superalloy comprises mainly γ′-phase (∼90%). The structure, distribution and morphology of γ′-phase is determined.
