Dynamics and fragility of the metallic alloy NiSi
Nickel based alloys are important materials with high strength up to high temperatures. Alloying nickel changes various physical properties like strength, liquidus temperature or its solidification behaviour. The aim of this experiment is to study the relaxation/diffusion dynamics in the binary alloy NiSi towards solidification in the liquid and supercooled state. The aerodynamic levitation set-up from CNRS Orleans for the IN6 spectrometer will be applied. By changing the composition we are able to change the fragility of the alloy. The temperature dependence will deliver the transition temperature from a strong to a fragile liquid. We aim to indentify a slow relaxation process which initiates solidification.
