A hypothetical eutectic phase diagram for metals A and B shows that cooling a liquid melt with a concentration of 50 wt% A-50 wt% B to just below 625 °C (eutectic isotherm temperature) results in simultaneous formation of alpha and beta phases. The phase diagram also shows that alpha (A rich) and beta (B rich) phases exist at left and right extremes of the phase diagram, respectively. At the eutectic isotherm temperature, the maximum solubility of B in A and A in B is 10 wt% and 5 wt%, respectively. The phase diagram does not have any intermetallic compounds.
