Compressive Behavior of a Zr‐Based Metallic Glass at Cryogenic Temperatures

Abstract

Cold compression: The compressive behavior of the as-cast fully amorphous Zr57.4Cu17.9Ni13.4Al10.3Nb1 alloy has been conducted at room temperature (298 K) and at liquid-nitrogen temperature (77 K). It is found that at cryogenic temperatures, at the same strain rate, the strength of the material increases remarkably without any loss of ductility (see figure).
