摘要

Stress driven nucleation of nanocrystals in amorphous alloys has been a subject of intensive debate in the past decade.

It has long been postulated that nanocrystals form succeeding the occurrence of shear bands in deformed amorphous alloys. In this study

we show

via

in situ

nanoindentation of amorphous Cu

alloy in a transmission electron microscope that the formation of nanocrystals occurred at an ultra-low stress of 0.25 GPa in the elastic deformation regime

accompanied by load-drops without evidence of shear bands. Furthermore

during successive loading

repetitive nanocrystal nucleation events were observed

and the stress required for nucleation kept on increasing to ∼0.54 GPa

implying the occurrence of a ‘hardening’ effect in the amorphous alloy. This study provides direct evidence to advance our understanding on deformation-induced nanocrystallization of amorphous alloys.
