Interpretation: Obtain phases present, concentration of phases and their fraction (%). Solvus line: limit of solubility Eutectic or invariant point. Liquid and two solid phases exist in equilibrium at the eutectic composition and the eutectic temperature. The melting point of the eutectic alloyis lower than that of the components (eutectic = easy to melt in Greek).• At most two phases can be in equilibrium within a phase field.• Single-phase regions are separated by 2-phase regions.
