摘要

Abstract

BSTRACTThe plasticity of metallic glasses depends largely on the atomic-scale structure. However

the details of the atomic-scale structure

which are responsible for their properties

remain to be clarified. In this study

in-situ

high-energy synchrotron X-ray diffraction and strain-rate jump compression tests at different cryogenic temperatures were carried out. We show that the activation volume of flow units linearly depends on temperature in the non-serrated flow regime. A plausible atomic deformation mechanism is proposed

considering that the activated flow units mediating the plastic flow originate from the medium-range order and transit to the short-range order with decreasing temperature.
