摘要

Abstract

BSTRACTJohari–Goldstein (JG) relaxation closely relates to the shear transformation zones (STZs) in the flow of metallic glasses (MGs). However

the actual role played by JG relaxation in the STZ-evoked plastic deformation of MGs remains unknown. In this work

by substituting the transition metal (TM) element in La(TM)Al MGs (TM = Ni

CuNi) to tune the feature of JG relaxation

how JG relaxation alters the deformation behaviors of MGs is tentatively examined with nanoindentation. The results demonstrate that JG relaxation modulates the anelastic to plastic transition rate in the plastic deformation accommodation of MGs via a characteristic relaxation time.
