Abstract

Cu–Co–Fe alloys undercooled below a certain temperature display demixing of the liquid, followed by coagulation before dendritic solidification. In this article high temperature phase equilibria in Cu–Co–Fe samples have been precisely determined by DSC. Special attention has been paid to the liquid–liquid phase separation and on its effect on the formation of microstructures. The measured transformation temperatures have also been used to update the description of the ternary phase diagram.
