Rapid solidification of indium: Modeling subcooling

This paper deals with the study of crystallization kinetics. A pure metal – indium – is subjected to different cooling rates by analyzing phenomena with a differential scanning calorimeter. Thanks to the thermal flux obtained by this device and to the temperature determined with a thermocouple inside the metal sample, and according to the modified Avrami theory, the aim was to determine a temperature dependent function K which links thermodynamic properties to a macroscopic model of crystallization kinetics. Experiments highlight the recalescence phenomenon and show that this function has a shape similar to that of the nucleation rate.
