Abstract

Extrusion of Zr₄₄Ti₁₁Cu₁₀Ni₁₀Be₂₅ bulk metallic glass in its supercooled liquid state is explored as a method to create objects of a fixed cross-sectional profile. The effect of processing parameters and extrusion geometries on the extrusion length is determined. The results reveal the nature of the flow process as creeping flow. Profile lengths of up to 50 cm are achieved using a 2-mm diameter die with a tapered length which theoretically results in a zero effective die length.
