Abstract

The micro-back-extrusion forming process of a Zr₅₅Cu₃₀Ni₅Al₁₀ bulk metallic glass (BMG) in its supercooled liquid state was studied. Based on the understanding of rheological properties of the BMG, the optimum conditions for extrusion were found to be a temperature of 725 K and an extrusion strain-rate of ∼1 × 10^-2 s^-1. Finite-element analysis was used to obtain the corresponding extrusion speed. As a result, a three-dimensional cup-shaped object with wall thickness of 0.05 mm was successfully produced.
