Metallic nanostructures such as tips, rods, tubes, and wires are backbones to construct nanoscale devices and characterization of size-effects in metals. However, these technological and scientific advancements are hampered by the complex and expensive lithography based fabrication of metallic nanostructures. Here, we present a novel hot-drawing technique where metallic glasses (amorphous metal alloys) are elongated the supercooled liquid state to form controllable nanostructures. This approach allows facile fabrication of various structures such as nano-tips, nanowires, micro-cones and microwires without nanolithography. The flow behavior of metallic glass supercooled liquids is tuned through temperature and strain rate to control the shape of resulting structures upon elongation and rupture. Quantitative studies on individual structures are performed to understand the correlation between the initial size/shape, temperature (viscosity), drawing speed (strain rate), and final shape/size.
