In a two-phase region of a phase diagram, such as solid+liquid, we can determine the composition of each phase from horizontal tie-lines and their intersection with the solidus and liquidus lines. We can also see evidence of a solubility limit by examining lattice parameter as a function of composition. If it's linear across the composition ...
