... in aluminum from the beryllium that remains in solid solution. It has also been reported that there may be a metastable miscibility gap in the liquid-plus-solid region of the diagram. If this is so, it allows a rapidly cooled alloy to separate into two phases in the liquid state and the subsequent formation...

... . When the temperature goes below the critical temperature, a miscibility gap exists where a single-phase homogenous microstructure is no longer stable and a two-phase, α 1 + α 2 , structure forms. The phase boundary on the phase diagram at temperature T ′ is given by the locus of points of common...

..., alloys containing between 36 and 87 wt% Pb separate into two liquids on further cooling. The two liquids coexist in the miscibility gap, or dome, that is typical of all alloys that undergo a monotectic reaction. During solidification of a copper-lead alloy containing 20 wt% Pb, the copper-rich α phase...

..., and the components of some of these systems are completely soluble, or miscible, in each other in the solid form, thus forming a continuous series of solid solutions. When this occurs in a binary system, the phase diagram usually has the general appearance of the copper-nickel system shown in Fig. 6.3 . Temperature...
