Micro- to nano-scale characterisation of the morphology, structure and composition of γ΄ precipitate populations in a new nickel-base superalloy

Abstract:

The emerging need to reduce CO2 emissions, while simultaneously improving the efficiency of aeroengines drives the continuous quest for new nickel-base superalloy formulations with improved thermal and mechanical properties. Aiming to expand the operational limits of superalloys outside the current envelope, higher γ′ volume fraction alloys have been developed considering the fundamental role of γ′ precipitation in the high temperature mechanical performance. The main objective of this stu...
