“…It can be seen that many shear bands form on the plastic deformation zone. According to our earlier work [24], micro-hardness of the vit1 could be decreased as a result of the generation of shear bands.…”

A Zr41.2Ti13.8Cu12.5Ni10Be22.5 (vit1) bulk metallic glass was processed by Nd: Glass laser pulses with duration 30ns and energy in the range 20 to 30J. The surface morphology and surface micro-hardness of the vit1 metallic glass, treated with varying laser energy, had been studied in detail. Laser shock peening induced plastic deformation and caused a micro-dent to be generated on the vit1 surface. The optical profiling tests showed that laser pulse energy greatly influenced the diameter and depth of the micro-dents. The surface roughness which was caused by various laser pulse energy was assessed and characterized. The three-dimensional surface topography of the laser treated region on vit1 surfaces had been characterized. In addition the plastic deformation features were also studied.

“…Bulk metallic glass (Zr41.2Ti13.8Cu10Ni12.5Be22.5 (vit1)) was laser peened by Zhu et al [28] who reported that LSP increased surface roughness and hardness decreased by up to 13%. The softening effect was attributed to the high-density shear-bands induced by the LSP.…”
