Preparation and super-plastic deformation of the Zr-based bulk metallic glass

Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass rods with an aspect ratio of 25:1 were prepared by suction casting and water quenching methods. A suitable temperature region for super-plastic deformation of the bulk metallic glass was determined by thermal expansion experiments, and the bulk metallic glass was found to exhibit excellent super-plastic deformation ability in this temperature region.
