Abstract

The effects of nanosecond laser peening on Zr41Ti14Cu12.5Ni10Be22.5 metallic glass were investigated in this study. The peening treatment produced an extra-deep shock-affected zone compared to crystal metal. As opposed to the conventional shear bands numerous arc shear bands appeared and aggregated in the vertical direction of the laser beam forming basic units for accommodating plastic deformation. The arc shear bands exhibited short and discrete features near the surface of the material then grew longer and fewer at deeper peened layer depths which was closely related to the laser shock wave attenuation. An energy dissipation model was established based on Hugoniot Elastic Limit and shear band characteristics to represent the formation of an extra-deep shock-affected zone. The results presented here suggest that the bulk modification of metallic glass with a considerable affected depth is feasible. Further they reveal that nanosecond laser peening is promising as an effective approach to tuning shear bands for improved MGs ductility.
