Abstract
Cyclic thermal analysis is used to study the effect of overheating ΔT+ of a melt on the presolidification supercooling \(\Delta T_{{\text{L}}}^{ - }\) of gallium–indium alloys. The existence of deep supercooling \(\Delta T_{{\text{L}}}^{ - }\) with respect to the liquidus is found for hypoeutectic alloys, whereas, for hypereutectic alloys, the supercooling is found only with respect to solidus TE (eutectic transformation line). The activities and the coefficients of activity of constituents are calculated at the onset of quasi-equilibrium and nonequilibrium explosive solidification. When the composition approaches the eutectic one, the activity of both constituents is found to decrease.
