Analysis of the Gibbs Energy during the Formation of Eutectics

Russian Metallurgy (Metally) Aims and scope

Abstract

Dependences of free Gibbs energies GL and GS on the component content and temperature are analyzed for binary eutectic alloys, which are characterized by terminal solid solubility and are present in liquid (L), liquid–solid (LS), and solid (S) states. Using additional Gibbs energy GLS for the liquid–solid state, conditions for the most stable alloys in this region and melting (and solidification) paths during L → LS → S transitions are determined.
