Abstract
A rapid defect-printing (RDP) treatment for achieving macroscopic tensile plasticity in a monolithic Zr-based bulk metallic glass (BMG) is proposed. Obvious yielding and certain tensile plasticity are observed for the RDP-treated BMG samples. The surface defects introduced, such as geometrical and mechanical heterogeneities, facilitate the formation of multiple shear band zones and the homogenization of plastic deformation . The proposed RDP treatment may shed light on the structural application of conventional BMGs with large critical size but poor plasticity.
