Hugoniot-compression curve of Zr-based bulk metallic glass

Abstract

The Hugoniot-compression curves of the Zr-based bulk metallic glass (Zr55Al10Ni5Cu30 in at. %) and the metallic compound crystal with the same composition were measured by means of the inclined-mirror photographic technique. A kink was observed on the Hugoniot curve at 14GPa for the glass probably due to phase transition, while no kink was observed for the crystal. The Hugoniot elastic limit stress (6.2GPa) of the glass was comparable to one of the crystal.
