Notes:
Bulk metallic glass (BMG) exhibits remarkable properties such as high strength, goodstiffness and good corrosion resistance. However, the wear resistance of amorphous metals is notexcellent as expected their high strength. It is thought that large local shear bands easily change intocracks for debris formation. The effective obstruction of shear band formation might be applied toimprove the wear resistance of BMG. In this study, we tried to suppress shear band deformation byfine crystalline phase dispersion formed by semi-conductor laser irradiation. The microstructures ofirradiated Zr-based BMG specimens were characterized by X-ray diffraction (XRD) and scanningelectron microscope (SEM). The fine dispersions of crystalline phases are observed in the amorphousmatrix. The optimum condition for laser irradiation was discussed
