|Abstract: ||It has been well documented that the plastic deformation of bulk
metallic glasses is localised in thin shear bands. In order to
comprehensively understand deformation mechanisms of BMGs, it is
necessary to investigate formation of shear bands and related deformation.
Nano-indentation studies with a spherical indenter were carried out to
characterise shear-band localisation on a surface of Zr-Cu-based metallic
glass. The load-displacement diagram of an indentation cycle reflects an
elastic deformation followed by the first pop-in at around 4 mN. In
addition, an alternative technique is proposed to characterise a plasticity
mechanism through the evolution of localised shear bands beneath the
indentation – wedge indentation. It is found that a hemicylindrical region of
shear bands is formed beneath the indentation zone in this case.|
