Study of the microscopic dynamics during a liquid-liquid transition in a supercooled metallic melt

The proposal aims to solve the evolution of the microscopic dynamics of a metallic melt during a liquid-liquid transition. The system to study shows this transition in the deeply super-cooled liquid state at temperatures where the melt has characteristic relaxation times in the order of seconds, which can be resolved by the new capabilities offered by XPCS at ESRF-EBS. The experiment proposed will explore the anomalous dynamics observed at the liquid-liquid transition in macroscopic measurements and, in addition, will test the possibility of resolving the super-cooled liquid dynamics while heating at constant rates, thus bypassing the limitation due to the easy crystallization at this temperature region.
