    Dynamic shear punching is employed to process Zr36.6Ti 31.4Nb7Cu5.9Be19.1 metallic glass matrix composites. A brittle fracture dominates during punchforming, and no macroscopic cracks or ruffles can be found, indicative of a good surface finish. The softening instability for metallic glasses happens once the yielding is available, avoiding the existence of shear bands and achieving smooth surfaces. No crystallization is accompanied in the heavy deformation zones during dynamic shear punching. The thickness of punched sheets for various BMG systems is highly dependent on the shear strengths. Furthermore, it is deduced that larger glass-transition temperatures of BMGs correspond to the thinner punched sheets, which provides a theoretical guidance to rapidly process metallic glass sheets.
