摘要

Abstract

Experimental differentiation of individual strengthening effects from the nanoscale precipitates in Alloy 718 remains challenging due to co-precipitation of

′ and

′′. Here

we examine a region adjacent to the

-phase consisting of

-matrix containing

′-precipitates only. The width and compositional profile of this

′′-free zone is uncovered via high-resolution characterization. Nanomechanical analyses reveal that the lack of

′′-precipitates lower the hardness of the

′′-free zone by 10–20%

while the

-phase is found to be ∼80% harder than the

-matrix. These findings may guide mechanical modelling and microstructural engineering of stronger superalloys critical to aerospace industry.
