摘要

Abstract

Studying the flow behavior is critical to understand the deformation mechanism of amorphous solids. However

detecting the basic flow events in amorphous solids is challenging. Here

by simultaneous SAXS/WAXS

elementary flow carriers in wound metallic glasses are identified from flow-induced structural heterogeneities with a radius of gyration of 2.5∼3.5 nm. Their size increases and morphology changes from sphere-like to rod-like under flow. Moreover

the atomic structure exhibits an unusual change to a more disordered state during winding/annealing at the temperature of ∼0.8 T

. This work provides an atomic-to-nanoscale description of the flow carriers of amorphous solids during deformation.

Impact Statement

The elementary flow carriers in metallic glasses have a radius of gyration of 2.5∼3.5 nm. During flow

their size increases and morphology changes from sphere-like to rod-like.
