Investigating the Effects of Aluminum Additions in $Cu_{55-x}Zr_{45}Al_{x}$ Metallic Liquids

Metallic glasses, their applications and structure are topics of interest within the condensed matter community. In this work, systematic additions of aluminum in the poor bulk glass forming alloy $Cu_{55-x} Zr_{45}Al_{x}$ (x = 0-10) provide the means to track structural evolution with compositional changes. In all compositions studied, a crossover temperature $T_{S}$ is observed. This work provides insight into the viability of the metric $T_{S}$ as a fundamental indicator of glass forming ability since the value of $T_{S}$ may change as the glass forming ability changes.
