Abstract

The metastable miscibility gap of Fe-Cu alloys in the undercooled liquid state was experimentally studied using a high temperature thermoanalytical method. Applying the melt fluxing technique it was possible to reach undercooling levels up to 250 K. Thus, the miscibility gap could be determined in the wide composition range between 10 at.% and 88 at.% Fe, showing symmetrical shape. Additionally, the specific heat in the liquid and undercooled liquid state was measured. A strong temperature dependence of the liquid specific heat was observed, which can be described in the framework of the self-association model.
