摘要

Abstract

The chemical short-range orders (CSRO) are the sub-nanosized entities inherent in high-/medium-entropy alloys (H/MEA). To discern CSRO poses the challenge with pending issues as to under what zone axis in electron diffraction

signature scattering specific to CSRO will appear and what the structure motif of CSRO is. Here

we show extra diffuse scattering by CSRO from [111] and [112] directions in a VCoNi MEA and accordingly

construct the L11-type structure motif

and derive the spacial shape of flat cuboid of CSRO in virtue of diffractions under varying zone axis. Moreover

we demonstrate the methods to identify CSRO in lattice images.
