摘要

Abstract

BSTRACTThe size-dependent hardness

strain-rate sensitivity (SRS) and shear transformation zone (STZ) volume of co-sputtered Cu–Zr metallic glass films with film thickness

spanning from 1000 to 3000 nm were systematically investigated by nanoindentation creep tests at room temperature. Experimental results manifested an exceptional decrease in hardness and a monotonic increment in SRS (or a monotonic decline in STZ volume) with reducing

. The deformation mechanism could be rationalized in light of more free volume combined with smaller STZs in thinner films

which likely trigger the strain-softening behavior. Moreover

STZs and deformation-induced devitrification promote the homogeneous-like plastic flow.
