Abstract Differential scanning calorimetry (DSC) combined with an entrained droplet technique [1] has been successfully used on a series of melt spun alloys with deliberate impurity additions to study the nucleation related aspects of secondary phase selection during solidification of dilute Al alloys. This paper illustrates how DSC is a sensitive tool for determining the effect impurities can have on the nucleation of secondary phases, and hence material properties of these alloys. Stepped cooling/isothermal holding profile DSC has also been used in preliminary investigations of the thermodynamic range of formation of the Al—Fe eutectic phases and their nucleation and growth solidification kinetics.
