PPT-Eutectic Phase Diagram construction using Free

E nergy vs Composition C urves To construct free energy vs composition curves given a eutectic phase diagram and vice versa Learning Objectives . DEVELOPMENT OF MICROSTRUCTURE IN. EUTECTIC ALLOYS. Depending on composition, several different types of microstructures are possible for the slow cooling of alloys belonging to binary eutectic systems.. INTRODUCTION. At sea level.

Binary diagrams have two components. We therefore usually choose to plot both T (temperature) and X (composition) with pressure held constant. P-X (T fixed) or P-T (X fixed) are also possible.
