资源简介：
A gradient nanostructure was prepared in aged Inconel 718 by means of surface mechanical grinding treatment
at room temperature. At the top surface layer with a thickness of ~50 μ m, the grain was refined down to
extremely fine size (~10 nm) and an abnormal Cr enrichment was detected on the grain boundaries. This Cr-
segregated extremely-fine nanograin exhibits an unprecedented yield strength of ~2935 MPa and superior GB
stability against coarsening upon 800 ◦C annealing, providing a new sight on the preparation of superalloy with high performance.
