Abstract

Adopting cyclic superheating and DSC analysis, solidification behavior of undercooled Cu₇₀Fe₃₀ alloy was investigated. The metastable phase separation is observed if the initial melt undercooling (ΔT) is above 56 K. The primary solidification of Fe-rich phase in the phase-separated melt is due to its high nucleation driving force i.e. a high ΔT. The coarsening of Fe-rich droplets is controlled by ΔT and can be ascribed to the Ostwald ripening and coagulation effect in the melt.
