Abstract Scope |
Amongst the most fundamental quantities for the description of a metallic glass (MG) are the viscosity η(T) and the fragility parameter, which are commonly related to the glass forming ability. Measuring these is challenging and data have only been reported for few compositions and systems. By contrast, no comprehensive experimental data exist thus far to reveal how the viscosity and fragility change within a system across a wider composition range. Fundamental questions therefore remain unanswered, for example whether the fragility and the glass forming ability are directly correlated for MGs. Here, we present first experimental strategies and results to measure the viscosity and fragility across wide composition ranges and across various MG systems. Since cost and required time per MG composition are comparatively small, we aim to implement these strategies in a high-throughput fashion. |
